Fix NPE in DFSClient.getFileChecksum
------------------------------------

                 Key: HDFS-2065
                 URL: https://issues.apache.org/jira/browse/HDFS-2065
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 0.23.0
            Reporter: Bharath Mundlapudi
            Assignee: Bharath Mundlapudi
             Fix For: 0.23.0


The following code can throw NPE if callGetBlockLocations returns null.

If server returns null 

{code}
    List<LocatedBlock> locatedblocks
        = callGetBlockLocations(namenode, src, 0, Long.MAX_VALUE).getLocatedBlocks();
{code}

The right fix for this is server should throw right exception.
