Arun C Murthy updated MAPREDUCE-3240: ------------------------------------- Priority: Blocker (was: Major) > NM should send a SIGKILL for completed containers also > ------------------------------------------------------ > > Key: MAPREDUCE-3240 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3240 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2, nodemanager > Affects Versions: 0.23.0 > Reporter: Vinod Kumar Vavilapalli > Assignee: Hitesh Shah > Priority: Blocker > Fix For: 0.23.0 > > Attachments: MR-3240.1.patch, MR-3240.2.patch, MR-3240.3.patch, > MR-3240.wip.patch > > > This is to address the containers which exit properly after spawning > sub-processes themselves. We don't want to leave these sub-process-tree or > else they can pillage the NM's resources. > Today, we already have code to send SIGKILL to the whole process-trees > (because of single sessionId resulting from setsid) when the container is > alive. We need to obtain the PID of the containers when they start and use > that PID to send signal for completed containers' case also. -- This message is automatically generated by JIRA.
