[jira] [Updated] (MAPREDUCE-3787) [Gridmix] Improve STRESS mode

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3787?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Graves updated MAPREDUCE-3787:
-------------------------------------

    Fix Version/s:     (was: 0.23.1)
                   2.0.5-beta
                   3.0.0

this was actually only fixed in trunk.  I merged this back into branch-2 also.

> Gridmix STRESS mode can be improved as follows:
> 1. The sleep time in JobMonitor can be reduced and/or made configurable
> 2. Map and reduce load calculation in StressJobFactory can be done in one loop
> 3. Updating the overload status from the job submitter thread (inline)
> 4. Optimizations to avoid un-necessary progress check (which inturn would result into delay)
