-----------------------------------

             Summary: MiniDFSCluster may still be partially running after initialization fails.
                 Key: HDFS-6678
                 URL: https://issues.apache.org/jira/browse/HDFS-6678
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 3.0.0, 2.5.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Minor


{{MiniDFSCluster}} initializes the daemons (NameNodes, DataNodes) as part of object construction.
 If initialization fails, then the constructor throws an exception.  When this happens, it's
possible that daemons are left running in the background.  There is effectively no way to
clean up after this state, because the constructor failed, and therefore the caller has no
way to trigger a shutdown.
