Yu Li commented on HBASE-17138:
-------------------------------
So here I'd like we make a consensus on whether to 1) backport HBASE-11425 to
branch-1 or 2) upload our patches for our customized 1.1.2 here. The former is
more official and means community will maintain the backported feature, but as
[~anoop.hbase] mentioned there'll be some more efforts to keep compatibility so
more than only HBASE-11425, and the latter is easier for us but harder for
others to use due to code-base diverge.
Maybe some kind of voting in need here? +1 for backport and -1 for only
uploading existing patches? Let me know your thoughts please, thanks.

And comments from others are also welcome. Thanks.

> Echoing some comments from the mail thread:
> Bryan:
> Is the backported patch available anywhere? If it ends up not getting
> officially backported to branch-1 due to 2.0 around the corner, some of us
> who build our own deploy may want to integrate into our builds
> Andrew:
> Yes, please, the patches will be useful to the community even if we decide
> not to backport into an official 1.x release.
> Enis:
> I don't see any reason why we cannot backport to branch-1.
> Ted:
> Opening a JIRA would be fine. This makes it easier for people to obtain the
> patch(es)
> Nick:
> From the DISCUSS thread re: EOL of 1.1, it seems we'll continue to
> support 1.x releases for some time... I would guess these will be
> maintained until 2.2 at least. Therefore, offheap patches that have seen
> production exposure seem like a reasonable candidate for backport, perhaps in
> a 1.4 or 1.5 release timeframe.
> Anoop:
> Because of some compatibility issues, we decide that this will be done in 2.0
> only.. Ya as Andy said, it would be great to share the 1.x backported
> patches.
