JAVA_HOME file is not working and I couldn't update Java to 1.8 on Amazon EC2

I have an Amazon EC2 t3.medium instance on Linux.
I am trying to run Apache ni-fi on this instance and I need java.
When I check the JAVA_HOME default:
$ echo$JAVA_HOME
-bash: echo/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.261-2.6.22.2.amzn2.0.2.x86_64: No such file or directory
Then, I downloaded java 1.8 by the following comamnds on terminal:
$ sudo yum install java-1.8.0-openjdk.x86_64
$ sudo update-alternatives --config java
(I selected 2 for java 1.8)
To find the location of my java file, I run them:
$ file $(which java)
/usr/bin/java: symbolic link to `/etc/alternatives/java'
$ file /etc/alternatives/java
/etc/alternatives/java: symbolic link to `/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64/jre/bin/java'
$ file /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64/jre/bin/java
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64/jre/bin/java: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 3.2.0, BuildID[sha1]=1b1c0fd721197a04f9bfc9b0891f1bd83a5f49d5, not stripped
I guess it is working properly. Then, I change JAVA_HOME from 1.7 to 1.8 by writing these commands on terminal for both ec2-user and root:
[root#ip-178-32-11-247 ~]# export JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64"
[root#ip-178-32-11-247 ~]# PATH=$JAVA_HOME/bin:$PATH
In advance, I have setup nifi on root. And in nifi-1.16.0 directory, I am trying to run this command:
[root#ip-178-32-11-247 nifi-1.16.0]# bin/nifi.sh start
The Error message is:
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64
NiFi home: /root/nifi-1.16.0
Bootstrap Config File: /root/nifi-1.16.0/conf/bootstrap.conf

I thought that java is working but JAVA_HOME couldn't setup properly but I couldn't solve that. What should I do at that point to solve the problem and start nifi?
I will be appreciated very much if you can help, I coludn't start my term project because of this error :(

The correct path for JAVA_HOME should be /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64/jre/bin/java
export JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.amzn2.0.2.x86_64/jre/bin/java"
But probably you don't need to export JAVA_HOME anyway. You should have a link in /usr/bin/. You can check this by doing the following:
[ssm-user#ip-172-31-85-243 bin]$ which java
/usr/bin/java
By default Apache Nifi is using the executable /usr/bin/java, so you don't need to export JAVA_HOME.

"Unable to run a simple JNI program" error message when installing rJava on R 3.6 for ubuntu bionic beaver

I have the very common problem that rJava does not install correctly on Ubuntu.
This problem has been dsicussed in multiple places here, here, here, to name a few.
The basic problem is that on installing the rJava package, the following error message is produced
configure: error: Unable to run a simple JNI program. Make sure you have configured R with Java support (see R documentation) and check config.log for failure reason.
Warning in system(cmd) : error in running command
ERROR: configuration failed for package ‘rJava’
* removing ‘/home/jonno/R/x86_64-pc-linux-gnu-library/3.6/rJava’
There are various closely related solutions to this problem. Most of them use sudo R CMD javareconf to configure Java for R (also a -e variant). Some suggest setting the JAVA_HOME path in the environment variables (others say not to). Others suggest uninstalling and re-installing R whilst others suggest installing rJava from cran. There are several who reccomend update alternatives. There are other variants of these solutions.
I have tried combinations of all of the above, and have got nowhere, so am clearly doing something wrong.
entering echo $JAVA_HOME returns
/usr/lib/jvm/java-11-openjdk-amd64
my etc/environment looks like this
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/$
MKL_THREADING_LAYER=GNU
JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"
When I run R CMD javaconf, it looks like this

Done.
What am I doing wrong and how do I get rJava to install properly?
EDIT:
having managed to successfully install rJava using sudo apt-get install r-cran-rjava I know get the following error
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/usr/lib/R/site-library/rJava/libs/rJava.so':
libjvm.so: cannot open shared object file: No such file or directory

I've investigated with the original poster (we work at the same place) and the problem is that in OpenJDK11 they moved around some of the .so files that the JVM lives in, specifically libjvm.so which in the Ubuntu package is now in /usr/lib/jvm/java-1.11.0-openjdk-amd64/lib/server/.
This means that even if you install the Ubuntu package for rJava with apt install r-cran-rjava it fails when you try to library(rJava).
The solution is to add /usr/lib/jvm/java-1.11.0-openjdk-amd64/lib/server/ to your $LD_LIBRARY_PATH by adding:
export LD_LIBRARY_PATH=/usr/lib/jvm/java-1.11.0-openjdk-amd64/lib/server:$LD_LIBRARY_PATH
to the end of your ~/.bashrc and starting a new shell (or source ~/.bashrc).
This is something we had to fix for our central installs of OpenJDK e.g. here: https://github.com/UCL-RITS/rcps-buildscripts/blob/master/adoptopenjdk-11.0.3_install.sh#L46
If you want to make this work with Rstudio launched from Gnome, you need to add that directory to ldconfig.
As root (or with sudo) create a file in /etc/ld.so.conf.d/ which you should call something with a .conf extension e.g. java.conf which contains the line:
/usr/lib/jvm/java-1.11.0-openjdk-amd64/lib/server
And then as root run
ldconfig -v
This should add the directory to the locations that executables launched through GNOME search for. This particular part of the problem (GNOME ignoring settings in bashrc) has been a problem in Ubuntu since at least 9.04 (https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/366728/).

Permissions error running Java Timezone Updater JAR in Dockerfile

RUN which java
RUN ["/usr/bin/java", "-jar", "tzupdater.jar", "-v", "-l"]
I thought that every Dockerfile command was run as root? But when I try to build from this Dockerfile, I'm running into this permissions issue which also happened in my local environment when I forgot to run this JAR as sudo:
$ docker build -t container-w-tz-update .

I was able to run this utility as sudo on my local with the exact same version of Java with no issues. When I tried to run it locally without sudo, I received the same error. Thoughts?

(This is more like a comment but the message length is beyond the comment limit, so I leave it here as an answer so that other people can maybe give more useful info based on what I've done.)
Seems it's really an unresolved issue, I reproduced your problem by image enoniccloud/java6 running with root user, I also tried docker run -it --privileged ... to run it manually but it does not help. I also tried jdk8 with base image alpine:3.3 but also failed with:
Downloaded file to /tmp/tz.tmp/sha512hash

Validating for : tzdata2017b
Validation complete
JRE updated to version : tzdata2017b
I searched and the only info I found is as follows:
An open issue: https://github.com/docker/hub-feedback/issues/896
Related but not the same: https://forums.docker.com/t/update-docker-container-jre-to-set-timezone-correctly/24426
Before you find the root cause for this issue, I think an alternative way to build your image could be:
Download a JDK tarball for your platform
Untar it, setup JAVA_HOME and PATH, run java -jar tzupdater.jar -v -l on your host
Build your base image based on this updated JDK, ADD to image and setup environment variable like JAVA_HOME and PATH
Hope this could be helpful to you :-)

docker build will complete RUN steps as the last USER set in the Dockerfile.
To reset:
RUN whoami
USER root
RUN ["/usr/bin/java", "-jar", "tzupdater.jar", "-v", "-l"]
USER "whatever whoami reported"

I got a workaround for that. Adding some mv commands (that have no real effect) made it work:
FROM openjdk:7u211-jdk-alpine3.9
ADD tzupdater.jar tzupdater.jar
RUN mv /usr/lib/jvm/java-1.7-openjdk/jre/lib/zi /usr/lib/jvm/java-1.7-openjdk/jre/lib/zi.tzdata2018g && \
mv /usr/lib/jvm/java-1.7-openjdk/jre/lib/zi.tzdata2018g /usr/lib/jvm/java-1.7-openjdk/jre/lib/zi && \
java -jar tzupdater.jar -v -l https://.../tzdata-latest.tar.gz
I have no idea why it works, I got it by trial and error.
Notice the two mv commands do like mv a b && mv b a, so nothing really changes.
The names of the files (dirs, actually) used in the mv are the ones it outputs when it errors (before the workaround), so change it accordingly.

Unable to install rJava in R 3.0 in Ubuntu 13.04

I am not able to call rJava package in R 3.0. I got the following message
Error: package ‘rJava’ was built before R 3.0.0: please re-install it
I am getting error when I tried to re-install rJava package. I have provided the output of R CMD javareconf

I am using Ubuntu 13.04. I also tried apt-get install r-cran-rjava which is not helping to solve the issue. Regarding jni.h there were some solution here. But, not sure how can I use the solution here.

I ran into the exact same issue. My solution was to install the openjdk-7-* via
sudo apt-get install openjdk-7-*
Followed that with
sudo R CMD javareconf
and I was then able to install rJava in R via install.packages("rJava").
While perhaps not the most elegant solution it appears to have solved my problems with getting rJava to work.

For those getting the error:
error: unable to load shared object '/some/dir/rJava/libs/rJava.so': libjvm.so:
cannot open shared object file: No such file or directory
I solved the error locating the library in the system and linking them to /usr/lib:
$sudo updatedb
$locate libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/zero/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/jamvm/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/zero/libjvm.so
$sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so /usr/lib/

Installing rJava from the distribution packages as proposed in this askUbuntu answer also works:
sudo apt-get install r-cran-rjava
NOTE: tried from a Debian system.

I was also facing same error which was on RHEL8.1 & i resolved it as follows:
yum --enablerepo=* install java-1.8*
later i ran same command which was giving me error logs of R server.
R CMD javareconf
which turns into following output.

error: unable to load installed packages just now

When I tried to run the R console in Eclipse, I got this error:
....Please make sure that R package 'rj' (1.1 or compatible) is installed...
So I tried to install it in the R console like this:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")
and got this error:
** testing if installed package can be loaded
Error : .onLoad failed in loadNamespace() for 'rj.gd', details:

and I found that when installing rJava using: install.packages("rJava") gets a similar error:

by the way,my configuration is:

For Linux(Ubuntu) users: If you have oracle-java (7/8) installed. It'll be at this location /usr/lib/jvm and sudo access is required.
Create the file /etc/ld.so.conf.d/java.conf with the following entries:
/usr/lib/jvm/java-8-oracle/jre/lib/amd64
/usr/lib/jvm/java-8-oracle/jre/lib/amd64/server
(Replace java-8-oracle with java-7-oracle depending on your java version)
Then:
sudo ldconfig
Restart RStudio and then install the rJava package.
OR
Also an alternative method is to export LD_LIBRARY_PATH with the value of Java library path obtained from the command R CMD javareconf -e and run install.packages

I got similar issue and was able to resolve it by running
R CMD javareconf -e
Output of the R CMD javareconf -e

After setting LD_LIBRARY_PATH to the same value as JAVA_LD_LIBRARY_PATH as shown in the output above. I was able to install rj.
export LD_LIBRARY_PATH=/export/apps/jdk/JDK-1_6_0_27/jre/lib/amd64/server:/export/apps/jdk/JDK-1_6_0_27/jre/lib/amd64:/export/apps/jdk/JDK-1_6_0_27/jre/../lib/amd64:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
Run R and then install rj by
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")

I found the solution:
export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-oracle/lib/amd64:/usr/lib/jvm/java-7-oracle/jre/lib/amd64/server
then
sudo R CMD javareconf
Note: The path (java-7-oracle) needs to be updated based on your Java installation.

I did the following and it worked for me:
export LD_LIBRARY_PATH=$JAVA_LD_LIBRARY_PATH
sudo R CMD javareconf
I had to restart R then as well.

Years later, I ended up on this question after searching for an error reported by R after I had unsuccessfully installed a package on that required shifting to Oracle's Java.
All I had to do to fix it was:
$ sudo R CMD javareconf

or just set the library in R?
I just ran this command in R:
Sys.setenv(JAVA_HOME='/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server')
(replace "/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server" with your Java library path which can be found running "sudo R CMD javareconf")
Might not be the most elegant solution - but it worked for me!

I did not had the jdk installed which I could fix with
sudo apt-get install jdk-*
After that i could run the sudo R CMD javareconf which always drew an error message before. Everything was set correctly and no manual tweeks where required, and after that package installation ran smootly in R (restart required).

When facing missing limjvm.so errors make sure that the correct ldpaths is picked up from the standard configuration in /etc/R versus the one in /usr/lib/R/etc.

This fixes the LD_LIBRARY_PATH problem for me (Linux, Debian 7.1.0, tc-shell, R version 3.0.2):
Add this line to .cshrc:
setenv LD_LIBRARY_PATH $JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server
Adding this command to ~/.login was not enough; the environment variable LD_LIBRARY_PATH was still not known in new xterms: echo $LD_LIBRARY_PATH : LD_LIBRARY_PATH: Undefined variable. (Why??)
Curiously, when starting R as superuser, there was no problem with finding libjvm.so .

I fixed this by just running R with sudo, and then running install.packages('rJava`).

None of the above worked for me, the only solution that installed rJava on Linux Ubuntu without any problems was to pass RScript command after installation of the base R:
$ sudo Rscript -e 'install.packages("rJava", repos = "http://cran.r-project.org/")'
