Subject [jira] [Commented] (HBASE-10569) Co-locate meta and master
Date Wed, 09 Apr 2014 17:42:38 GMT

Lars Hofhansl commented on HBASE-10569:
---------------------------------------

Thanks for writing this up. If the active HMaster only holds META that should be fine, it'd
be moved/recovered quickly. Local writes are great, no cross machine coordination needed.

> 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.
