[jira] [Updated] (MAPREDUCE-3141) Yarn+MR secure mode is broken,
uncovered after MAPREDUCE-3056
[ https://issues.apache.org/jira/browse/MAPREDUCE-3141?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vinod Kumar Vavilapalli updated MAPREDUCE-3141:
-----------------------------------------------
Component/s: applicationmaster
Priority: Blocker (was: Major)
Affects Version/s: 0.23.0
After MAPREDUCE-3056 went in, I ran single node secure setup which is breaking with YARN+MR.
I see that single node secure setup is now identical to a multi-node setup only after MAPREDUCE-3056. Before that, MRAppMaster(run on the same node) used to pick up kerberos tokens from the local token-cache which was filled during job-submit(again on the same node); so in a sense single node-setup wasn't the same as multi-node secure setup.
I suspect MAPREDUCE-3006 to have broken this code, but surprised that others haven't run into this.
