Subject [jira] [Commented] (YARN-4593) Deadlock in AbstractService.getConfig()
Date Thu, 14 Jan 2016 20:51:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15098826#comment-15098826

Steve Loughran commented on YARN-4593:
--------------------------------------

SLIDER-1052 shows this. I'm not going to blame this JIRA for that, but it's certainly where
the problem arises

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: yarn
>    Affects Versions: 2.7.2

> SLIDER-1052 has found a deadlock which can arise in it during AM restart. Looking at
the thread trace, one of the blockages is actually {{AbstractService.getConfig()}} —this
is synchronized and so blocked.
