Unable to run applications using oozie successfully. Jobs are stuck in PREP mode forever

[#1]

Hi, we have spun up a cluster using Cloudbreak on EC2 instances. We tried sample wordcount application using hadoop jar command and the map-reduce action was successful along with sqoop import using command line which was successful as well. But when we started running these same actions using oozie. The jobs are getting stuck in PREP state forever.

Issue is similar to previously posted : https://community.hortonworks.com/questions/114512/oozie-actions-stuck-in-prep-state.html

Can someone help us to determine what might be causing this problem? Thanks.

I was using incorrect job-tracker ip address. Make sure to check the ResourceManager ip address for job-tracker.
