Datanodes need to catch SocketTimeoutException and UnregisteredDatanodeException
--------------------------------------------------------------------------------

         Key: HADOOP-289
         URL: http://issues.apache.org/jira/browse/HADOOP-289
     Project: Hadoop
        Type: Bug

  Components: dfs  
    Versions: 0.3.1    
    Reporter: Konstantin Shvachko
 Assigned to: Konstantin Shvachko 
     Fix For: 0.3.2


- 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.
