    Description

      1. allow snapshots under dir /foo
      2. create a file /foo/bar
      3. create a snapshot s1 under /foo
      4. delete the file /foo/bar
      5. wait till checkpoint or do saveNameSpace
      6. restart NN.
      7. Now try to read the file from snapshot /foo/.snapshot/s1/bar

      client will get BlockMissingException

      Reason is
      While loading the deleted file list for a snashottable dir from fsimage, blocks were not updated in blocksmap
