Subject [jira] Commented: (HADOOP-4655) FileSystem.CACHE should be ref-counted
Date Mon, 24 Nov 2008 20:39:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650315#action_12650315
] 

dhruba borthakur commented on HADOOP-4655:
------------------------------------------

If an application wants to release all the resources associated with an "open" filesystem,
it might want to use FileSystem.close(), isn't it? This might be worthwhile for an application
that opens many many different FileSystems (especially with different usernames) and then
closes them appropriately to release the amount of resources tied up with each open instance.

> FileSystem.CACHE should be ref-counted
