I am getting error when i run the command yarn logs -applicationId application_1532367457044_47155. I have attached yarn.txt file contains oozie job log. Kindly look into that.

Below output is the sample error of yarn logs saying driver issue when importing sqoop job in oozie. I gave oozie.libpath=${nameNode}/user/oozie/share/lib/lib_20180703052502/sqoop as libpath in job.properties.

I don't know where i am wrong , please help me out to find the solution.

For your kind info i have attached both workflow.xml and job.properties.

what should i change to get this work ??

You need the postgres java jar file. Below are similar commands I have to add the jar to ambari-server. You may need to get the jar files to your oozie job and or nodes oozie job is executing on:

Add postgres connector:

cd /usr/share/java
sudo wget https://jdbc.postgresql.org/download/postgresql-42.2.2.jar
sudo ambari-server setup --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-42.2.2.jar
sudo ambari-server restart

If this answer helps you please choose ACCEPT.

I tried restarting ambari server with JDBC driver as you mentioned and it's not working for me.

Anyway, thank you for your support.

when I see the errors in yarn logs with application id, repeatedly getting below error.

SqlManager-Error executing statement: java.sql.SQLException: No suitable driver found

looking for some other solution. Please help me

@Steven Matison

I made it work by passing sqoop command as arguments in workflow.xml.

Please have a look at my workflow.xml and job.properties file.

This is working absolutely fine.

job.properties:

nameNode=hdfs://(namenode):8020
jobTracker=(resourcemanager):8050/8032
queueName=default
oozieExecutionFolder=oozietest/sqoop
oozie.use.system.libpath=true
oozie.wf.application.path=${nameNode}/user/${user.name}/${oozieExecutionFolder}

workflow.xml:

    </kill>

</workflow-app>

Note:

sqoop commands should be passed within arguments otherwise job will not run. Additionaly you have to mention postgresql driver jar file path inside file tag in workflow.xml. The given configuration is more than enough to run oozie-sqoop job successfully.

Good to go !! 🙂
