> In HBASE-5162 (and backports such as HBASE-12729) we modified some HRegion
> methods to return statistics for consumption by callers. The statistics are
> ultimately passed back to the client as load feedback.
> [~lhofhansl] thinks handing back this information as return values from
> HRegion methods is a weird mix of concerns. This also produced a difficult to
> anticipate binary compatibility issue with Phoenix. There was no compile time
> issue because the code of course was not structured to assign from a method
> returning void, yet the method signature changes so the JVM cannot resolve it
> if older Phoenix binaries are installed into a 0.98.10 release. Let's change
> the HRegion methods back to returning 'void' and use setters instead.
> Officially we don't support use of HRegion (HBASE-12566) but we do not need
> to go out of our way to break things (smile) so I would also like to make a
> patch release containing just this change to help out our sister project.
