Deadlock in LocalDirsHandlerService and ShuffleHandler ------------------------------------------------------
Key: MAPREDUCE-3519 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3519 Project: Hadoop Map/Reduce Issue Type: Bug Components: nodemanager Affects Versions: 0.23.1, 0.24.0 Reporter: Ravi Gummadi Assignee: Ravi Gummadi Fix For: 0.23.1 MAPREDUCE-3121 cloned Configuration object in LocalDirsHandlerService.init() to avoid others to access that configuration object. But since it is set in the base class of LocalDirsHandlerService using super.init(conf), it is reflected and is accessible to some other services. This is causing a deadlock when accessing this configuration object from LocalDirsHandlerService and ShuffleHandler along with AllocatorPerContext object. -- This message is automatically generated by JIRA.
