[jira] [Created] (YARN-5436) Race in AsyncDispatcher can cause
random test failures in Tez(probably YARN also )

----------------------------------
Summary: 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 DrainedDispatcher was fixed. Unfortunately, it also exists in AsyncDispatcher but wasn't found. In YARN-2991, another DrainedDispatcher bug was fixed by letting DrainedDispatcher 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).
