> Use setters instead of return values for handing back statistics from HRegion
> methods
> -------------------------------------------------------------------------------------

> Key: HBASE-12979
> URL: https://issues.apache.org/jira/browse/HBASE-12979
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.98.10
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Labels: phoenix
> Fix For: 0.98.10.1
>
>
> 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 returning this information 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.
