Subject [jira] [Updated] (HBASE-11689) Track meta in transition
Date Wed, 20 Aug 2014 08:04:26 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11689?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrey Stepachev updated HBASE-11689:
-------------------------------------

    Attachment: HBASE-11689.patch

Made meta region state (currently single one) stored in zk.
That helps to track meta transition state. 
Additionaly that localises zk usage in AssigmentManager that implies only master able to update
this state. Previously meta location was updated by HRegionServer and HMaster.

Implemented as single call of setMetaLocation in RegionStateStore. 

Patch solves issue with ZookeeperProtos structures Master and MetaRegionServer which where
parsed by one method in ServerName class.

> With ZK-less region assignment, user regions in transition are tracked in meta. We need
a way to track meta in transition too.
