Bryan Beaudreault updated HBASE-27391:

Status: Patch Available (was: Open)
This created a massive amount of log spam in our environment, when running the
default state of having client pushback disabled. The spam was enough to show
up as a non-trivial amount of time on flamegraphs. This PR eliminates the log
spam and time spent.

> This method logs with ERROR level if the MultiResponse does not include
> RegionLoadStats. These stats may be disabled on the server side, and really
> this doesn't seem like an error state. We should downgrade to DEBUG since
> it's an optional feature that is not enabled by default.
