[jira] [Created] (HDFS-4748) MiniJournalCluster#restartJournalNode leaks resources, which causes sporadic test failures

Chris Nauroth created HDFS-4748:
-----------------------------------

             Summary: MiniJournalCluster#restartJournalNode leaks resources, which causes sporadic test failures
                 Key: HDFS-4748
                 URL: https://issues.apache.org/jira/browse/HDFS-4748
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: qjm, test
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
             Fix For: 3.0.0


{{MiniJournalCluster#restartJournalNode}} stops a {{JournalNode}} and then recreates a new one with the same configuration.  However, it does not maintain a reference to the new {{JournalNode}} instance, so therefore it doesn't get stopped inside {{MiniJournalCluster#shutdown}}.  The {{JournalNode}} holds a file lock on its underlying storage, so this can cause sporadic failures in tests like {{TestQuorumJournalManager}}.
