On master node : Failed construction of Regionserver : java.net.BindException - java

I have a 4-node cluster(hadoop 2.5.2) (Hbase 1.0.0) with a master(as salve) and 3 slaves on the master machine. After calling start-hbase.sh, the jps does not show the HRegionServer process running on the master but is ruuning fine on all the three slaves.
the log file on the master shows:

This is related to a number of issues in HBase 1.0.x: HBASE-11575, HBASE-13453 and HBASE-13479.
A workaround mentioned in this comment on HBASE-13479 is to manually configure the following ports in hbase-site.xml:
hbase.regionserver.port
hbase.master.info.port
hbase.regionserver.info.port
Upgrading to HBase 1.1.x is another option (worked for me).

In dockerized environment spark worker not able to resolve application host

We are running Spark as Docker microservice. My spark application able to submit the tasks to worker node, but worker node is not able to connect to application, throwing UnknowHostException. Basically worker node trying to communicate with application with containerId(658e5d214a60) which is not getting resolved to container IP.
It is working when I run these services with docker-compose yaml files in local Linux machine but failing in AWS EC2 container.

ClassNotFoundException when trying to add configuration to a CompositeConfiguration using commons-configuration2

I'm using org.apache.commons:commons-configuration2 to load and merge configuration from different sources:
val root = CompositeConfiguration()
root.addConfiguration(SystemConfiguration())
val configurations = Configurations()
root.addConfiguration(configurations.properties("defaults.properties"))
My problem is that whenever I run this code I get an exception:
Exception in thread "main" java.lang.NoClassDefFoundError:

It says that org.apache.commons.beanutils.BeanIntrospector is not found. If I add commons-beanutils:commons-beanutils:1.9.3 to the classpath the problem is solved but the main problem is that I'm using Apache Spark 2.3.0 in a managed environment (Databricks) and it comes with commons-beanutils:1.7.0 so I can't do anything about the beanutils version.
How can I solve this problem?
You may want to try using commons-configuration:commons-configuration:1.10 if you only want the composite configuration feature form commons-configuration. It works like this:
val root = CompositeConfiguration()
root.addConfiguration(SystemConfiguration())
root.addConfiguration(PropertiesConfiguration("defaults.properties"))
Configurations 2 won't work with 1.7.0 bean utils according to their documentation.

Intellij can't run Wildfly server

This is exactly the same I get as output in Intellij.
I found thanks to this topic that it may be a matter of user permissions.
However, when I try to add a user to wildfly with the add-user.sh script, I get this error : ./add-user.sh: 1: eval: /usr/lib/jvm/jdk1.8.0_60/bin/java: not found
It is looking for a wrong JDK path. I tried to change it following different solutions but none of them work.
My JAVA_HOME is set to /usr/lib/jvm/java-8-oracle .
Is any of you having an idea of what to do ? Thank you in advance :)
Forget the add-user.sh script. This is for adding users to wildfly. Your issue is with your Linux users.
The directory has to be writable by whatever user wildfly is running as.
If you are running it as a user named wildfly then you have to change the ownership of those directories to that user. According to your question it looks like you are running as some other user that does not have permissions to those directories.
If you want a quick easy fix and you aren't worried about other users on the system you could just change permissions like:
sudo chmod -R 766 /opt/wildfly/standalone/
This will give the owner all permissions, and other users read/write permissions to those directories.
This is not best practice. Best practice is to give that directory ownership to user 'wildfly' with permissions of 600. Then you should run wildfly as the 'wildfly' user on linux. Any startup script you can find will likely do this for you.

I'm trying using my local user, root user, changing ports (ie: run 8080), start instead of run, and it always throw the same exception.
By the way, port 9000 is not in use by another application.
Anyone has any clue?
I'm using Ubuntu 12.04 LTS, and Play Framework 2.2.6.
Thanks.
The error is that your port is being used by another process.
In a UNIX machine the command lsof -i:9000 will give the processes that are using the port.
As you have noted correctly processes with root permissions can be hidden if you use the terminal not as root

This is likely due to using Java 8 rather than Java 7. Even though you have installed Java 7 - perhaps you still have JAVA_HOME set to Java 8?
