Subject [jira] [Commented] (YARN-3480) Make AM max attempts stored in RMAppImpl and RMStateStore to be configurable
Date Fri, 08 May 2015 01:36:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-3480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14533731#comment-14533731

Jun Gong commented on YARN-3480:
--------------------------------

[~jianhe] just catch your option. Do you mean that the configure value for max attempts stored
in RMAppImpl and RMStateStore is not needed at all, we could just remove the attempts records
that's beyond the validity window? If so, I will update the 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.
