Subject [jira] [Commented] (HBASE-18511) Default no regions on master
Date Tue, 08 Aug 2017 04:51:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16117852#comment-16117852

stack commented on HBASE-18511:

I've set TABLES_ON_MASTER to a boolean for now. This issue is a little interesting. Trying
to figure how to do this tables on master (system, any, or none). Let me see what tests fail
now w/ these few fixes.

> Let this be umbrella issue for no-regions-on-master as default deploy (as it was in branch-1).
> Also need to make sure we can run WITH regions on master; in particular system tables
with RPC short-circuit as it is now in hbase master.
> Background is that master branch carried a change that allowed Master carry regions.
On top of this improvement on branch-1, Master defaulted to carry system tables only. No release
was made with this configuration. Now we are going to cut the 2.0.0 release, the decision
is that hbase-2 should have the same layout as hbase-1 so this issue implements the undoing
of Master carrying system tables by default (though the capability remains).
