Eric Payne commented on MAPREDUCE-3034: --------------------------------------- @Devaraj, Can you please upmerge the patch to the latest code in http://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.23 Thanks! > NM should act on a REBOOT command from RM > ----------------------------------------- > > Key: MAPREDUCE-3034 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3034 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2, nodemanager > Affects Versions: 0.23.0, 0.24.0 > Reporter: Vinod Kumar Vavilapalli > Assignee: Devaraj K > Priority: Critical > Attachments: MAPREDUCE-3034-1.patch, MAPREDUCE-3034-2.patch, > MAPREDUCE-3034-3.patch, MAPREDUCE-3034-4.patch, MAPREDUCE-3034.patch, > MR-3034.txt > > > RM sends a reboot command to NM in some cases, like when it gets lost and > rejoins back. In such a case, NM should act on the command and > reboot/reinitalize itself. > This is akin to TT reinitialize on order from JT. We will need to shutdown > all the services properly and reinitialize - this should automatically take > care of killing of containers, cleaning up local temporary files etc. -- This message is automatically generated by JIRA.
