Dear Learner,

Hope you are doing well.

To overcome the above error, please use the following steps:

Note: Please do not copy, paste the commands. Please try them by typing manually.

Firstly, stop oozie if it’s running.

        Command: cd /usr/lib/oozie-4.0.0/

        Command: ./bin/oozie-stop.sh

Make the below three changes needs to be done.

1. 

•    Edit hadoop’s core-site.xml

                   Command: sudo gedit /usr/lib/hadoop-2.2.0/etc/hadoop/core-site.xml

 

 

• Remove oozie and put edureka as mentioned in below screenshot, save the file and close it.

Restart the cluster.

               Command: sudo service hadoop-master stop

               Command: sudo service hadoop-master start

               Command: hadoop dfsadmin -safemode leave

• Edit your job.properties and workflow.xml files. Use jobTracker port as 8032 in both the files and oozie.wf.application.path as ${nameNode}/WordCountTest as mentioned in below snapshots.

                Command: sudo gedit Desktop/LMS/Oozie/WordCountTest/job.properties

 Command: sudo gedit Desktop/LMS/Oozie/WordCountTest/workflow.xml

Now you need to transfer the WordCountTest directory on hdfs ( / ).

              Command: hadoop dfs -put Desktop/LMS/Oozie/WordCountTest /

3

• Giving permissions to Oozie directory.

                 Command: sudo chmod -R 777 /usr/lib/oozie-4.0.0

                 Command: sudo chown -R edureka /usr/lib/oozie-4.0.0

• Now change the directory to Oozie and start it.

                 Command: cd /usr/lib/oozie-4.0.0/

                 Command: ./bin/oozie-start.sh

• Run the oozie command.

      Command: oozie job -oozie http://localhost:11000/oozie -config /home/edureka/Desktop/LMS/Oozie/WordCountTest/job.properties -run
