      Description

      HADOOP-2346 introduced data read/write timeout. when data stream borken, DFSClient will retry in read/write methods, but no such mechanism found when seek(long) calling blockReader.skip(diff) (DFSClient.java #1582), will let IOException throw to application. i met NPE when using MapFile in hbase.

      i'm supposing in the seek(long) method, let done be 'false' will causing retry (via 'blockEnd = -1'), a patch will attached later for review.
