> Allow module tests run in parallel

> Key: HBASE-24150
> URL: https://issues.apache.org/jira/browse/HBASE-24150
> Project: HBase
> Issue Type: Sub-task
> Components: build
> Reporter: Michael Stack
> Priority: Major
>
> Parent issue is about upping forkcount. This one is about mildly letting
> modules run tests in parallel. Parent wants forkcount to be 0.5C so we use
> half the processors. This is about keeping forkcount at 0.25C but allowing
> two modules to run their tests at same time when mvn figures it is possible.
> In a test on a local machine, using forkcount of 1.0C and -T == 1 -- default
> -- the full test suite took 1hr 15mins. With forkcount at 0.5 and T == 2,
> full suite took 53mins.
