             Summary: 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

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.
