          It turns out that the ClassCastException can be reproduced by the following.

          1. Create a new file with a full block.
          2. Append but not add any data so that the last block remains full and the last block in INodeFileUnderConstruction is a BlockInfo but not BlockInfoUnderConstruction.
          3. Append again.

          h3385_20120509.patch:

          • adds the test above;
          • fixes the indentation.

          I create HDFS-3394 for removing generic type from INodeFile.getLastBlock(), so that we could keep the patch simple in this issue.

          Thanks, Brahma. The last block of INodeFileUnderConstruction is not necessarily a BlockInfoUnderConstruction. I will try to add a test.

          We should also remove the generic from INodeFile.getLastBlock(). It is useless as shown here.

          Hi Nichalos..

          I have reproduced same..

          Scenario:
          --------
          write a file
          append a file so that it fails and close the clients
          again try to append the same file we will get ClassCastException.

          I verified your patch..it's fine..

          Brahma, thanks for filing the bug. Could you also check if h3385_20120508.patch works for your test case?

          The line numbers in the stack trace is off. If my guess is correct, the fix could be as simple as the following patch.

          It seems that ClassCastException is not shown up in the existing unit tests. How to reproduce this exactly? Could you give more details?

          (Let's remove the rpc stack trace in the description.)
