JobClient.getDelegationToken() returns NULL
-------------------------------------------
Key: MAPREDUCE-3380
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3380
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mr-am
Affects Versions: 0.23.0
Reporter: Alejandro Abdelnur
Priority: Blocker
Fix For: 0.23.1
The JobClient.getDelegationToken() method is returning NULL, this makes Oozie
fail when trying to get the delegation token to use it for starting a job.
What is seems to be happing is that Jobclient.getDelegationToken() calls
Cluster.getDelegationToken() that calls YarnRunner.getDelegationToken() that
calls ResourceMgrDelegate.getDelegationToken(). And the last one is not
implemented. (Thanks Ahmed for tracing this in MR2 code)
