Subject [jira] [Commented] (HBASE-18298) RegionServerServices Interface cleanup for CP expose
Date Fri, 22 Sep 2017 00:24:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16175708#comment-16175708

stack commented on HBASE-18298:
-------------------------------

Pardon. I've been away from this important issue. Let me get back to it by responding to your
response [~anoop.hbase].

I like your objection to why we can't use OnlineRegions, because it has write methods. Could
we just throw IllegalAccess if a CP tries to add/remove Regions? Or could we insert an immutable
OnlineRegions? Or make a subinterface that adds the editing methods? Let me look more at the
patch to see if my suggestion, a week later, even makes sense.

I like how you are working to not expose levers to CPs such as the #stop method.
