     [ https://issues.apache.org/jira/browse/MAPREDUCE-3751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Foley updated MAPREDUCE-3751:
----------------------------------

    Target Version/s: 2.0.0-alpha, 1.2.0  (was: 1.1.0, 2.0.0-alpha)
    
> Simplify job submission in gridmix
> ----------------------------------
>
>                 Key: MAPREDUCE-3751
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3751
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: contrib/gridmix, mrv2
>    Affects Versions: 0.23.0, 1.0.0
>            Reporter: Arun C Murthy

> Currently gridmix tries to gauge cluster load etc. and throttles job submission. This
makes it unpredictable and also is hard to support across MR1 and MR2. 
> I propose we simplify it to be:
> # Replay mode - Just submit jobs in the interval as in the original trace.
> # Stress mode - Compress the interval with a given factor for all jobs.
