> Key: HBASE-4847
> URL: https://issues.apache.org/jira/browse/HBASE-4847
> Project: HBase
> Issue Type: Improvement
> Components: build, test
> Affects Versions: 0.94.0
> Environment: build
> Reporter: nkeywal
> Assignee: nkeywal
> Priority: Minor
> Attachments: 4847_pom.patch, 4847_pom.v2.patch, 4847_pom.v2.patch,

> This will not revolutionate performances alone. We will win between 1 to 4
> minutes.
> But we win as well:
> - it's a step for parallelizing the tests
> - new tests are less expensive as they do not create a new jvm: it's a
> continuous win
> - it will allow to push it on dev env while having the same env on dev & on
> build, and 3 minutes are 10% of small + medium tests execution time.
> I will do a few "submit patch" to see if it works well before asking for the
> real commit.
