Szilard Nemeth commented on YARN-9788: -------------------------------------- Hi [~prabhujoseph], Latest patch LGTM, committed to trunk. Thanks [~pbacsko] for the review. Resolving jira. > Queue Management API does not support parallel updates > ------------------------------------------------------ > > Key: YARN-9788 > URL: https://issues.apache.org/jira/browse/YARN-9788 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacity scheduler > Affects Versions: 3.3.0 > Reporter: Prabhu Joseph > Assignee: Prabhu Joseph > Priority: Major > Attachments: YARN-9788-001.patch, YARN-9788-002.patch, > YARN-9788-003.patch, YARN-9788-004.patch, YARN-9788-005.patch, > YARN-9788-006.patch, YARN-9788-007.patch, YARN-9788-008.patch, > YARN-9788-009.patch, YARN-9788-010.patch, YARN-9788-011.patch > > > Queue Management API - does not support parallel updates. When there are two > parallel schedule conf updates (logAndApplyMutation), the first update is > overwritten by the second one. > Currently the logAndApplyMutation creates LogMutation and stores it in a > variable pendingMutation. This way at any given time there will be only one > LogMutation. And so the two parallel logAndApplyMutation will override the > pendingMutation and the later one only will be present. > The fix is to return LogMutation object by logAndApplyMutation which can be > passed during confirmMutation. This fixes the parallel updates. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
