Subject [jira] [Commented] (HDFS-4092) Update file deletion logic to support snapshot files
Date Wed, 24 Oct 2012 16:46:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13483376#comment-13483376

Suresh Srinivas commented on HDFS-4092:
---------------------------------------

+1 for the patch. This also has some dependency on HDFS-4107 right and that needs to be committed
first?

> 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.
