Steve Loughran commented on YARN-4593: -------------------------------------- No tests. I'd have to think of a way to recreate the deadlock then make sure it was gone. someone will need to look at the code instead > Deadlock in AbstractService.getConfig() > --------------------------------------- > > Key: YARN-4593 > URL: https://issues.apache.org/jira/browse/YARN-4593 > Project: Hadoop YARN > Issue Type: Bug > Components: yarn > Affects Versions: 2.7.2 > Environment: AM restarting on kerberized cluster > Reporter: Steve Loughran > Assignee: Steve Loughran > Attachments: YARN-4593-001.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
