Istvan Toth updated PHOENIX-6946:
---------------------------------
Affects Version/s: 5.1.3
5.2.0
> IndexTool wastes MR resources
> -----------------------------
>
> Key: PHOENIX-6946
> URL: https://issues.apache.org/jira/browse/PHOENIX-6946
> Project: Phoenix
> Issue Type: Bug
> Components: core
> Affects Versions: 5.2.0, 5.1.3
> Reporter: Istvan Toth
> Priority: Major
>
> For the new style indexing, IndexTool does little more than generate a custom
> scan opreration per guidepost, send it to the RS, then wait for the result.
> It is idling 99.99% of the time, yet it ties up a lot of (usually all) Yarn
> resources.
> We should be able to do this without MR, or at least consolidate this into a
> single mapper job (in which case we'd simply use the MR framework as a job
> scheduler)
