Subject [jira] [Commented] (HBASE-10915) Decouple region closing (HM and HRS) from ZK
Date Thu, 01 May 2014 17:21:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13986790#comment-13986790
] 

Mikhail Antonov commented on HBASE-10915:
-----------------------------------------

bq. But for assignment, we don't need any consensus, right? The ConsensusProvider naming is
a little bit confusing. With ZK-less region assignment, we need to come up another consensus
provider?

No, ConsensusProvider is one class and one instance per Server. For region assignment it would
be one more Consensus class (like CloseRegionConsensus), not another consensus provider.
