Subject [jira] [Commented] (YARN-1221) With Fair Scheduler, reserved MB reported in RM web UI increases indefinitely
Date Wed, 25 Sep 2013 22:52:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-1221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13778196#comment-13778196
] 

Siqi Li commented on YARN-1221:
-------------------------------

{code}
-      getMetrics().reserveResource(app.getUser(),
-          container.getResource());
{code}

The reason I removed the code above is that there is no corresponding
unreserve method got called. In addition, app.getUser() and
application.getUser() return the same user.

Maybe we could add getMetrics().unreserveResource(app.getUser(),
container.getResource());
into corresponding unreserve block.

As far as I saw from the webUI, the available memory never get decremented
when it allocates memory to mr jobs. It actually reflects the totally
memory
