    Description

      When I bring up a DataNode it gets a ClassCastException:

      Exception in thread "main" java.lang.ClassCastException: java.util.HashMap$Entry
      at org.apache.hadoop.dfs.DataNode.runAndWait(DataNode.java:907)
      at org.apache.hadoop.dfs.DataNode.main(DataNode.java:954)

      This was introduced by the patch for HADOOP-354.
