    [ https://issues.apache.org/jira/browse/HBASE-17138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15721697#comment-15721697 ] 

Yu Sun commented on HBASE-17138:
--------------------------------

yes, [~anoop.hbase] is right, there are some building blocks jira not under HBASE-11425, To resolve the merge conflicts I have totally backport about 77 patches to our customized branch, should I list the all the jira id I have backported as sub-task here for you and [~ram_krish] to check?

> From the [thread|http://mail-archives.apache.org/mod_mbox/hbase-user/201611.mbox/%3CCAM7-19%2Bn7cEiY4H9iLQ3N9V0NXppOPduZwk-hhgNLEaJfiV3kA%40mail.gmail.com%3E] of sharing our experience and performance data of read-path offheap usage in Alibaba search, we could see people are positive to have HBASE-11425 in branch-1, so I'd like to create a JIRA and move the discussion and decision making here.
> 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.
