DataNode gets stuck while shutting down minicluster

                 Key: HDFS-2213
                 URL: https://issues.apache.org/jira/browse/HDFS-2213
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
             Fix For: 0.23.0
         Attachments: stack.txt

I've seen a couple times where a unit test has timed out. jstacking shows the cluster is stuck
trying to shut down one of the DataNode HTTP servers. The DataNodeBlockScanner thread also
seems to be in a tight loop in its main loop.
