Jun Gong updated YARN-3480: --------------------------- Attachment: YARN-3480.14.patch > Recovery may get very slow with lots of services with lots of app-attempts > -------------------------------------------------------------------------- > > Key: YARN-3480 > URL: https://issues.apache.org/jira/browse/YARN-3480 > Project: Hadoop YARN > Issue Type: Sub-task > 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, YARN-3480.04.patch, YARN-3480.05.patch, > YARN-3480.06.patch, YARN-3480.07.patch, YARN-3480.08.patch, > YARN-3480.09.patch, YARN-3480.10.patch, YARN-3480.11.patch, > YARN-3480.12.patch, YARN-3480.13.patch, YARN-3480.14.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)
