Xuan Gong commented on YARN-5718: --------------------------------- +1 LGTM. [~djp] But I am worried about the back-incompatibility issue. Could you file a separate ticket to have a discussion on branch-2 and branch-2.8 for this ticket, please ? At the mean time, I will commit the patch into trunk. > TimelineClient (and other places in YARN) shouldn't over-write HDFS client > retry settings which could cause unexpected behavior > ------------------------------------------------------------------------------------------------------------------------------- > > Key: YARN-5718 > URL: https://issues.apache.org/jira/browse/YARN-5718 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager, timelineclient > Reporter: Junping Du > Assignee: Junping Du > Attachments: YARN-5718-v2.1.patch, YARN-5718-v2.patch, YARN-5718.patch > > > In one HA cluster, after NN failed over, we noticed that job is getting > failed as TimelineClient failed to retry connection to proper NN.

Thus, we should clean up these hard > code settings in YARN, include: FileSystemTimelineWriter, > FileSystemRMStateStore and FileSystemNodeLabelsStore. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
