Yep, have seen this twice today. On a different machine, I now get
an NPE from HFileTargetIT:

java.lang.NullPointerException
        at org.apache.hadoop.hdfs.MiniDFSCluster.startDataNodes(MiniDFSCluster.java:426)
        at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:284)
        at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniDFSCluster(HBaseTestingUtility.java:435)
        at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:603)
        at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:559)
        at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:528)
        at org.apache.crunch.io.hbase.HFileTargetIT.setUpClass(HFileTargetIT.java:103)


This seems vaguely familiar, I think the embedded HBase mini cluster
requires some particular networking setup. I'll try again tomorrow.

  Matthias
