Subject [jira] [Commented] (HDFS-2285) BackupNode should reject requests trying to modify namespace
Date Sun, 30 Oct 2011 04:47:32 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13139542#comment-13139542

Uma Maheswara Rao G commented on HDFS-2285:
-------------------------------------------

Thanks Konstantin for the Review!
I noticed it while uploading the patch. I kept the changes because that is some unused imports
cleanup, and we can not file any separate jiras for unused imports cleanups alone.
Anyway thanks for updating it.

Thanks
Uma
