Subject [jira] Commented: (MAPREDUCE-1900) MapReduce daemons should close FileSystems that are not needed anymore
Date Thu, 09 Sep 2010 22:36:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907806#action_12907806

Dan Adkins commented on MAPREDUCE-1900:

This patch breaks hadoop for me.  Can we reconsider it?

It is not safe to call


in order to close one filesystem connection.


It causes the parent JobTracker's FileSystem object to be closed as well, making it impossible
(for me) to successfully submit a job.
