[jira] [Resolved] (MAPREDUCE-5718) MR AM should tolerate RM
restart/failover during commit
[ https://issues.apache.org/jira/browse/MAPREDUCE-5718?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karthik Kambatla resolved MAPREDUCE-5718.
-----------------------------------------
Resolution: Won't Fix
Target Version/s: (was: )
With work-preserving RM/NM restart, one can run into this only when the AM dies or the node running the AM dies. This is no longer a regression when moving from MR1 to MR2.
Closing this as "Won't Fix" for now. Please re-open if needed.

> While testing RM HA, we ran into this issue where if the RM fails over while an MR AM is in the middle of a commit, the subsequent AM gets spawned but dies with a diagnostic message - "We crashed durring a commit".
