sandflee commented on YARN-3480: -------------------------------- one benefit in [~hex108]'s work is we wouldn't worry about AM' failure. In our production env, we don't expect apps to be killed because of AM's failure. > Make AM max attempts stored in RMAppImpl and RMStateStore to be configurable > ---------------------------------------------------------------------------- > > Key: YARN-3480 > URL: https://issues.apache.org/jira/browse/YARN-3480 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.6.0 > Reporter: Jun Gong > Assignee: Jun Gong > Attachments: YARN-3480.01.patch, YARN-3480.02.patch, > YARN-3480.03.patch > > > When RM HA is enabled and running containers are kept across attempts, apps > are more likely to finish successfully with more retries(attempts), so it > will be better to set 'yarn.resourcemanager.am.max-attempts' larger. However > it will make RMStateStore(FileSystem/HDFS/ZK) store more attempts, and make > RM recover process much slower. It might be better to set max attempts to be > stored in RMStateStore. > BTW: When 'attemptFailuresValidityInterval'(introduced in YARN-611) is set to > a small value, retried attempts might be very large. So we need to delete > some attempts stored in RMStateStore and RMStateStore. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
