Looks like this break the mini cluster. I see a ton of this in the logs:

> Delayed flush doesn't work causing flush storms.

> Key: HBASE-14922

> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 2.0.0, 1.2.0, 1.1.2
> Reporter: Elliott Clark
> Assignee: Elliott Clark
> Fix For: 2.0.0, 1.2.0, 1.3.0

> Attachments: HBASE-14922-v1.patch, HBASE-14922-v2.patch,
> HBASE-14922.patch

>
> Starting all regionservers at the same time will mean that most
> PeriodicMemstoreFlusher's will be running at the same time. So all of these
> threads will queue flushes at about the same time.
> This was supposed to be mitigated by Delayed. However that isn't nearly
> enough. This results in the immediate filling up and then draining of the
> flush queues every hour.
