[jira] [Updated] (YARN-8051)
TestRMEmbeddedElector#testCallbackSynchronization is flakey
[ https://issues.apache.org/jira/browse/YARN-8051?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jason Lowe updated YARN-8051:
-----------------------------
Affects Version/s: 2.10.0
2.9.1
2.8.4
3.0.2
3.1.1
Target Version/s: 2.10.0, 3.2.0, 2.9.2, 2.8.5, 3.0.4, 3.1.2 (was: 3.2.0)
Fix Version/s: 3.1.2
3.0.4
Thanks, [~rkanter]]! We've been seeing this fail on older builds, so I committed this to branch-3.1 and branch-3.0 as well. I'll put up a patch for branch-2 shortly since 2.x still compiles for JDK7.
