Subject [jira] [Commented] (YARN-1221) With Fair Scheduler, reserved MB reported in RM web UI increases indefinitely
Date Wed, 25 Sep 2013 22:26:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-1221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13778174#comment-13778174
] 

Sandy Ryza commented on YARN-1221:
----------------------------------

{code}
-    this.totalMB = availableMB + reservedMB + allocatedMB;
+    this.totalMB = availableMB;
{code}
Total MB should still include allocatedMB.  I agree that reservedMB should be removed from
it, but I think this is work for a separate JIRA.  This one is for dealing with why reservedMB
is calculated incorrectly.

{code}
-      getMetrics().reserveResource(app.getUser(),
-          container.getResource());
{code}
Can you explain the rationale behind removing this?
