Vinod Kumar Vavilapalli updated MAPREDUCE-5910: ----------------------------------------------- Target Version/s: 2.6.0 Fix Version/s: (was: 2.5.0) > MRAppMaster should handle Resync from RM instead of shutting down. > ------------------------------------------------------------------ > > Key: MAPREDUCE-5910 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5910 > Project: Hadoop Map/Reduce > Issue Type: Task > Components: applicationmaster > Reporter: Rohith > Assignee: Rohith > Attachments: MAPREDUCE-5910.1.patch, MAPREDUCE-5910.2.patch > > > The ApplicationMasterService currently sends a resync response to which the > AM responds by shutting down. The MRAppMaster behavior is expected to change > to calling resyncing with the RM. Resync means resetting the allocate RPC > sequence number to 0 and the AM should send its entire outstanding request to > the RM. Note that if the AM is making its first allocate call to the RM then > things should proceed like normal without needing a resync. The RM will > return all containers that have completed since the RM last synced with the > AM. Some container completions may be reported more than once. -- This message was sent by Atlassian JIRA (v6.2#6252)
