    Description

      There is a missing break statement in DataNode.DataXceiver.run() which sends DataXceiver into an infinite loop printing

      Faulty op: 82
      07/07/17 17:52:04 ERROR dfs.DataNode: DataXCeiver
      java.io.IOException: Unknown opcode 82in data stream
      at org.apache.hadoop.dfs.DataNode$DataXceiver.run(DataNode.java:742)
      at java.lang.Thread.run(Thread.java:595)

      Consequence of HADOOP-1134.

      Also a printout two lines below seems unnecessary.
      And another three lines below
      LOG.error("DataXCeiver", t);
      should be spelled DataXceiver
