Jason Lowe created MAPREDUCE-5513: ------------------------------------- Summary: ConcurrentModificationException in JobControl Key: MAPREDUCE-5513 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5513 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 0.23.9, 2.1.0-beta Reporter: Jason Lowe
JobControl.toList is locking individual lists to iterate them, but those lists can be modified elsewhere without holding the list lock. The locking approaches are mismatched, with toList holding the lock on the actual list object while other methods hold the JobControl lock when modifying the lists. -- This message is automatically generated by JIRA.
