Please share your job.properties & coordinator.properties file. check the lib path oozie.libpath in these files and see if the required jar is present.

When oozie triggers a job , it will check the jars in the lib path distribute the to all the nodes in the cluster for execution.

You may also want to verify the configs in oozie-site.xml
