[jira] [Commented] (YARN-4348) ZKRMStateStore.syncInternal should
wait for zkResyncWaitTime instead of zkSessionTimeout
[ https://issues.apache.org/jira/browse/YARN-4348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15005722#comment-15005722 ]
Tsuyoshi Ozawa commented on YARN-4348:
--------------------------------------
Found that testZKRootPathAcls fails because of time out with the patch. I will check it more deeper.

> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.7.2, 2.6.2
> Reporter: Tsuyoshi Ozawa
> Assignee: Tsuyoshi Ozawa
> Attachments: YARN-4348.001.patch, YARN-4348.001.patch, log.txt

>
> Jian mentioned that the current internal ZK configuration of ZKRMStateStore can cause a following situation:
> 1. syncInternal timeouts,
> 2. but sync succeeded later on.
> We should use zkResyncWaitTime as the timeout value.
