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-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
