[jira] [Updated] (MAPREDUCE-3751) Simplify job submission in
gridmix
[ https://issues.apache.org/jira/browse/MAPREDUCE-3751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Joseph Evans updated MAPREDUCE-3751:
-------------------------------------------
Target Version/s: 1.1.0, 2.0.0 (was: 1.1.0, 0.23.1)
> 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.
