Zhiyuan Yang commented on YARN-5436: ------------------------------------ Data race can cause RM stop without handling last enqueued event. > Race in AsyncDispatcher can cause random test failures in Tez(probably YARN > also ) > ---------------------------------------------------------------------------------- > > Key: YARN-5436 > URL: https://issues.apache.org/jira/browse/YARN-5436 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Zhiyuan Yang > Assignee: Zhiyuan Yang > > In YARN-2264, a race in DrainDispatcher was fixed. Unfortunately, it also > exists in AsyncDispatcher but wasn't found. In YARN-2991, another > DrainDispatcher bug was fixed by letting DrainDispatcher extend > AsyncDispatcher because AsyncDispatcher doesn't have such issue. However, > this shadows YARN-2264, and now similar race reappears in Tez unit tests > (probably also YARN unit tests also). -- 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
