The DN should stop running it's background threads fail
-------------------------------------------------------

                 Key: HDFS-2953
                 URL: https://issues.apache.org/jira/browse/HDFS-2953
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 1.0.0, 0.23.0
            Reporter: Eli Collins


The DN will currently will startup and run if one of its background threads (eg the block scanner, async disk service) fails while trying to start. Which in this cases gives you a running DN w/o a block scanner. The DN should fail to start if any of its necessary background threads (eg not xfer threads) fail to start (or fail later on during execution).

In trunk this should be per block pool, ie if one block pool can start but another cannot we should probably allow the DN to run with the block pools that can start.
