      Description

      TestJobStatusPersistency failed and contained DataNode stacktraces similar to the following :

      2008-03-07 21:27:00,410 ERROR dfs.DataNode (DataNode.java:run(976)) - 127.0.0.1:57790:DataXceiver: java.net.SocketTimeoutException: 0 millis

      This is mostly related to HADOOP-2346. The error is strange. socket.getRemoteSocketAddress() returned null implying this socket is not connected yet. But we have already read a few bytes from it!.
