------------------------------------
Summary: IndexTool wastes MR resources
Key: PHOENIX-6946
URL: https://issues.apache.org/jira/browse/PHOENIX-6946
Project: Phoenix
Issue Type: Bug
Components: core
Reporter: Istvan Toth
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)
