[jira] [Commented] (HBASE-8217) Port online region merge (HBASE-7403) to 0.94

    [ https://issues.apache.org/jira/browse/HBASE-8217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13616920#comment-13616920 ] 

Elliott Clark commented on HBASE-8217:
--------------------------------------

I'm -1 on backporting this.

Reasons:
* In my opinion 0.94 is feature complete at this time.  
** I feel very strongly that it's incorrect to add new non bug fix code to 0.94.  
** 0.94.x has been our stable release for quite a while. We shouldn't destabilize that.
** Databases should not add features to point releases.
* This is experimental in trunk.
* This relies on very new code that hasn't been proven yet.
* Doesn't have integration tests.
* There a lot of edge cases.  
** Mixed version clusters
** Rolling upgrades while merging
** Reference files
** Merging daughter regions
** multiple merges with reference files
** merging while disabling
** merging while schema edits
* Users have gotten by without this for a long time; for me this really suggests that the need for this in an old version is pretty low.

> HBASE-7403 added online region merge, and there was some discussion about whether we can port this to 0.94. 
> In this issue, we can discuss feasibility and decide one what way or the other. I actually have a patch on top of backported HBASE-7721.
