ClassNotFoundException: org.apache.hadoop.conf.Configuration Starting Flink SQL Client

I'm trying to set up the Hive integration with Flink as shown here. I have everything configured as mentioned, all services (Hive, MySQL, Kafka) are running properly. However, as I start a Flink SQL Client on a standalone local Flink cluster with this command:
./bin/sql-client.sh embedded
I get a ClassNotFoundException: org.apache.hadoop.conf.Configuration...
This is the detailed log file with the exception trace:

Do you have any hint about what I'm missing? I have all my Hadoop libraries on my Classpath and I don't understand why this class is missing...
I'm using Flink 1.10 and Java 8
Also, this line in the log file makes me wonder if it really my mistake:
2020-04-01 11:27:32,776 ERROR org.apache.flink.table.client.SqlClient - SQL Client must stop. Unexpected exception. This is a bug. Please consider filing an issue.
Thank you in advance!

if you not add the HADOOP_HOME in you env, you can export the HADOOP_CLASSPATH, before run the ./bin/sql-client.sh embedded
export HADOOP_CLASSPATH=`hadoop classpath`

Hadoop Yarn job: Wrong FS

I installed a cloudera cluster with a vagrant box.
I get an error when I launch the following example:

Does anyone has an idea?
Thx

Change the property yarn.nodemanager.remote-app-log-dir in yarn-site.xml config file either to:
<property>
<name>yarn.nodemanager.remote-app-log-dir</name>
<value>hdfs://cdh-master:8020/var/log/hadoop-yarn/apps</value>
</property>
or
<property>
<name>yarn.nodemanager.remote-app-log-dir</name>
<value>/var/log/hadoop-yarn/apps</value>
</property>
The second option will use the default filesystem that should be set to HDFS anyway.

How to run nutch 1.9 in eclipse on windows?

I want to run Nutch 1.9 in Eclipse on Windows. I followed the tutorial from http://wiki.apache.org/nutch/RunNutchInEclipse and opened the project in Eclipse.
But when I run Nutch, I get the following error:

It seems that Hadoop is the causing error. I don't know how to solve this problem. I know Nutch requires Unix environment. But, I want to run Nutch in Eclipse on Windows.
Can anybody help me to solve this?

Download cygwin, then add that to your path of the environment variables. I think your problem is caused by the fact that windows can't invoke a unix native command. That is what I did however as soon as i got past that problem, I encountered other problems.

Cannot register pig UDF jar

I'm having problems with a particular UDF jar and have so far been unable to figure out where to begin. I have a way of testing the jar from the command line and it works. If I REGISTER the jar in a pig script, pig fails to create a jar for the job. I can register other jars without trouble and this jar was working until a few days ago. Here is the output when running the pig script:

Based on this I would think the problem is from the "java.util.zip.ZipException: invalid distance too far back" exception. Is pig having some issue reading the jar?

Apache Pig: unable to run my own pig.jar and pig-withouthadoop.jar

I have a cluster running Hadoop 0.20.2 and Pig 0.10.
I'm interested to add some logs to Pig's source code and to run my own Pig version on the cluster.
What I did:
built the project with 'ant' command
got pig.jar and pig-withouthadoop.jar
copied the jars to Pig home directory on the cluster's namenode
run a job
Then I've got following std output:

what went wrong? Should I do anything else except replacing pig.jar and pig-withouthadoop.jar in installation directory of namenode?
help...

the point I missed was: pig-withouthadoop.jar should be compiled with specific Hadoop version.
I compiled the jar in following way and it worked:
% ant clean jar-withouthadoop -Dhadoopversion=23
