    Description

      The following code can throw NPE if callGetBlockLocations returns null.

      If server returns null

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

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