Subject [jira] [Commented] (MAPREDUCE-4323) NM leaks sockets
Date Thu, 07 Jun 2012 18:15:24 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291175#comment-13291175

Tsz Wo (Nicholas), SZE commented on MAPREDUCE-4323:
---------------------------------------------------

This looks like a problem of the newly added socket cache.  Once it is fixed (say, it is removed
for the sake of discussion), are there other problems?
