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)
