---------------------------------------

[~jamestaylor] I don't see the long timeout anymore.  Does v4 look ok to you?

> In UngroupedAggregateRegionObserver#preCompact we call DefaultStatisticsCollector.createCompactionScanner. 
It uses the env config which in turn contains the RS server rpc timeout of 20 minutes.  That's
too long for a compaction hook.
> Like in PHOENIX-4169, we should cap the timeout so the compaction doesn't get blocked.
