Subject [jira] Commented: (HADOOP-4647) NamenodeFsck creates a new DFSClient but never closes it
Date Mon, 17 Nov 2008 18:35:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12648234#action_12648234

Tsz Wo (Nicholas), SZE commented on HADOOP-4647:
------------------------------------------------

> Does this mean that the NameNode might leak a few socket descriptors every time an fsck
is invoked?

This is probably the case.  Also, it leak a thread each time in 0.17.  All this leaking happen
when running fsck with -move.
