---------------------------------------
I tried running test locally to see if I could repro. I seemed to at first but
now it just passes all the time.

> Project: HBase
> Issue Type: Bug
> Reporter: Michael Stack
> Priority: Major
>
> I see this in recent nightly fails on branch-2, my experimental branch. It
> happened in the two builds last night. It was only test to fail. Both failed
> with:
> 2020-04-10 07:42:46,700 WARN [Time-limited test]
> regionserver.MultiVersionConcurrencyControl(228): STUCK:
> MultiVersionConcurrencyControl{readPoint=8684, writePoint=8686}
> I ran the test in my harness and it pushes up against heap limits for sure,
> especially after recent cut down in forked jvm size.
> For now, see if alleviating scope of testWritesWhileScanning just when called
> from this test helps w/ flakeyness. Probably worth a deep dive why we get
> into this state w/ in-memory compaction.
