Alejandro Abdelnur commented on MAPREDUCE-3380: ----------------------------------------------- John, you are correct, there are 2 different things. #2 should be implemented properly to work in secure clusters. #1 should be fixed to allow working when there is no delegation token available. Currently we are hitting #1 when trying to run Oozie against 0.23 > JobClient.getDelegationToken() returns NULL > ------------------------------------------- > > Key: MAPREDUCE-3380 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3380 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: mr-am > Affects Versions: 0.23.0, 0.24.0 > Reporter: Alejandro Abdelnur > Priority: Blocker > Fix For: 0.24.0, 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) -- This message is automatically generated by JIRA.
