Description

• Datanode needs to catch SocketTimeoutException when registering otherwise it goes down
  the same way as when the namenode is not available (HADOOP-282).
• UnregisteredDatanodeException need to be caught for all non-registering requests. The data
  node should be shutdown in this case. Otherwise it will loop infinitely and consume namenode resources.
