      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.

          Hi Bharath,

          I assumed this may happen when we create an empty file and make a call to getFileChecksum. But that doesn't seems to be the case. Even in empty file scenario this call doesn't throw any NPE.

          Can you please provide the scenario or stack trace for this. That will be helpful to reproduce and provide the correct fix.

          Bharath,

          There are some more scenarios for getBlockLocations returning null values. i.e, when we call getFileCheckSum on non existing files or directories, it will throw NullPointerException. These two conditions handled in HDFS-2509

          I think we need to clean some places, where it is checking for null values from getBlockLocations.
          See the code below from NameNodeFsck

          LocatedBlocks blocks = namenode.getNamesystem().getBlockLocations(path, 0,
                  fileLen, false, false);
              if (blocks == null) { // the file is deleted
                return;
              }
          

          Also can you please provide one Unit test for this scenario, which should illustrate that, when inode.getBlocks() will return null?

          Thanks
          Uma

          I suggest we simply change null in DFSClient.getFileChecksum(..) in this issue since it is a bugs in 0.20. We may think if FSNamesystem.getBlockLocation(..) should be changed seperatedly.

          +1 Patch looks good. Thanks!

          One nite: could you put locatedblocks = blockLocations.getLocatedBlocks(); in one line?

          Although getLocatedBlocks() won't return null in trunk, could you also post a similar patch for trunk? It is good to check null and your patch also adds a test.

          Updated patch for trunk!
          Handled null checks, because blockManager#createLocatedBlocks can return null when node.getBlocks return null. I did not find any direct scenario to replicate it. Added the same test cases for trunk.

          Thanks
