Date Fri, 19 Oct 2012 22:20:12 GMT
Tsz Wo (Nicholas), SZE created HDFS-4092:
--------------------------------------------

             Summary: Update file deletion logic to support snapshot files
                 Key: HDFS-4092
                 URL: https://issues.apache.org/jira/browse/HDFS-4092
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: name-node
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Tsz Wo (Nicholas), SZE


When snapshots are created, the blocks are shared among the snapshot files and the original
file.  Deletion of the snapshot file or the original file does not necessarily lead to deletion
of the blocks.  The deletion logic needs to be updated.
