Subject [jira] [Commented] (HBASE-10569) Co-locate meta and master
Date Wed, 14 May 2014 18:25:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10569?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13997854#comment-13997854

Jonathan Hsieh commented on HBASE-10569:
----------------------------------------

I thought that is what we agreed upon old topology default for 1.0 and new topology default
for trunk/2.0 during the pow-wow.

My vote is to keep the old topology for hbase 1.0, but have the option to go new in 1.0. 
For 2.0/trunk, we default to the new topology.  The old topology is well understood operationally
for deploys.  Though straightforward for us devs, I think having a brand new deployment style
with gotcha's we haven't figured out at scale with yet is risky for what we want to be a super
stable release.

> I was thinking simplifying/improving the region assignments. The first step is to co-locate
the meta and the master as many people agreed on HBASE-5487.
