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
