Vinod Kumar Vavilapalli updated MAPREDUCE-3399: ----------------------------------------------- Resolution: Fixed Fix Version/s: 0.23.1 Release Note: Modified ContainerLocalizer to send a heartbeat to NM immediately after downloading a resource instead of always waiting for a second. Hadoop Flags: Reviewed Status: Resolved (was: Patch Available) I just committed this to trunk and merged into branch-0.23. Thanks Sid! > ContainerLocalizer should request new resources after completing the current > one > -------------------------------------------------------------------------------- > > Key: MAPREDUCE-3399 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3399 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: mrv2, nodemanager > Affects Versions: 0.23.0 > Reporter: Siddharth Seth > Assignee: Siddharth Seth > Priority: Blocker > Fix For: 0.23.1 > > Attachments: MR3399_v1.txt, MR3399_v2.txt > > > Currently, the ContainerLocalizer to NM heartbeats to the NM every second. > Not very significant, but this causes a ~4second delay in jobs (job jar, > splits, etc). Instead, it should heartbeat to ask for additional resources to > localize as soon as the previous one is localzied. There's already a TODO in > the ContainerLocalizer for this. -- This message is automatically generated by JIRA.
