Subject [jira] Commented: (HDFS-677) Rename failure due to quota results in deletion of src directory
Date Fri, 09 Oct 2009 17:03:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12764099#action_12764099
] 

Suresh Srinivas commented on HDFS-677:
--------------------------------------

adding the node back is similar operation that is not expected to fail (just like swap in
the above case needs to be). BTW any failure such as OOM or NN crash etc. will result in client
receiving failure and this operation is not recorded in edits log. When NN restarts, src would
still be in the namespace as expected.
