This feature was deployed to a production cluster @ EBay running code base very close to 0.92.

------------------------------
Your comment is specious. FB are not running 0.92. Neither are EBay last I heard and if it is a 0.92, its not an Apache 0.92?

------------------------------
I think we should be careful what we backport, especially to old branches. We cannot afford to ship a point release that is less stable than those that precede it, especially one made from an old branch. Backporting features, especially invasive big changes, is one sure way of destabilizing code base.

Will post to dev@ list.
This feature has been in production @ Facebook and EBay. It is a stable feature.

We should be putting bug fixes into point releases? (This is marked as a bug but seems like a feature to me).

Ted Yu commented on HBASE-6726:
-------------------------------
There were 145 improvements in 0.92.2:
https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12319888&styleName=Text&projectId=12310753&Create=Create&atl_token=A5KQ-2QAV-T4JA-FDED|20dd5912cca928036b1ca12dd6edb463220c0a85|lin
And there were 21 new features in 0.92.2
I think this feature is very important for our users.
