Jason Lowe commented on YARN-8193: ---------------------------------- bq. The build failed due to some reason not related to the patch: The problem can be seen in the precommit log: {noformat} Switched to branch 'branch-2.9.0' Your branch is up-to-date with 'origin/branch-2.9.0'. HEAD is now at 756ebc8 HADOOP-15036. Update LICENSE.txt for HADOOP-14840. (asuresh) {noformat} The patch is targeting branch-2.9.0 which does not have HADOOP-15375 which fixed the cert error during the build. I will upload the same patch against branch-2, the next place this should be committed before committing to branch-2.9, which does have the cert fix. The patch applies cleanly, so it's the same bits. Hopefully this will result in a useful Jenkins run. > YARN RM hangs abruptly (stops allocating resources) when running successive > applications. > ----------------------------------------------------------------------------------------- > > Key: YARN-8193 > URL: https://issues.apache.org/jira/browse/YARN-8193 > Project: Hadoop YARN > Issue Type: Bug > Components: yarn > Reporter: Zian Chen > Assignee: Zian Chen > Priority: Critical > Fix For: 3.2.0, 3.1.1 > > Attachments: YARN-8193-branch-2-001.patch, > YARN-8193-branch-2.9.0-001.patch, YARN-8193.001.patch, YARN-8193.002.patch > > > When running massive queries successively, at some point RM just hangs and > stops allocating resources.
