Subject [jira] [Commented] (HBASE-11574) hbase:meta's regions can be replicated
Date Wed, 27 Jul 2016 06:50:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15395143#comment-15395143

Devaraj Das commented on HBASE-11574:
-------------------------------------

Done adding release note. [~stack] I don't have a cluster handy but from what i recollect,
the master webUI should show the replicas of the meta if you poke around. Also, the master
logs would have logs that speak to the fact that replicas of meta are getting created. Finally,
look at the test testShutdownHandling() in TestMetaWithReplicas .. it kills the primary meta
replica server, and then makes sure that the client can still reach the secondary locations
of the meta and get the locations of the regions of his table.

> As mentioned elsewhere, we can leverage hbase-10070 features to create replicas for the
meta tables regions so that: 
>  1. meta hotspotting can be circumvented 
>  2. meta becomes highly available for reading
