> Default StoreHotnessProtector to off, with logs to guide when to turn it on

> Key: HBASE-26814
> URL: https://issues.apache.org/jira/browse/HBASE-26814
> Project: HBase
> Issue Type: Improvement
> Reporter: Bryan Beaudreault
> Assignee: Bryan Beaudreault
> Priority: Major
> Fix For: 2.5.0, 2.6.0, 3.0.0-alpha-3
>
>
> As discussed in HBASE-26522 and somewhat in HBASE-26575,
> StoreHotnessProtector is too conservative. One can easily trigger
> RegionTooBusyException on an otherwise idle regionserver with relatively
> small amount of traffic. The idea behind this protection is good, but it
> needs to take into account current load in order to warrant being enabled by
> default.
> Until it's improved as such, we should change it to default off. One thing we
> can do to help drive usage would be to add warning logs when it would have
> triggered. Operators who are diagnosing performance issues will naturally
> look at the logs and see indication of a potential tool for mitigation.
