Subject [jira] [Resolved] (MAPREDUCE-2107) Emulate Memory Usage of Tasks in GridMix3
Date Wed, 15 Jun 2011 11:44:47 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2107?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Amar Kamat resolved MAPREDUCE-2107.

             Tags: gridmix heap-usage
       Resolution: Fixed
    Fix Version/s: 0.23.0
         Assignee: Amar Kamat  (was: Ravi Gummadi)
     Release Note: Adds total heap usage emulation to Gridmix. Also, Gridmix can configure
the simulated task's JVM heap options with max heap options obtained from the original task
(via Rumen). Use 'gridmix.task.jvm-options.enable' to disable the task max heap options configuration.

I just committed the latest patch to trunk. Thanks Ravi and Vinay!
