> Key: HBASE-2694
> URL: https://issues.apache.org/jira/browse/HBASE-2694
> Project: HBase
> Issue Type: Sub-task
> Components: master, regionserver
> Reporter: Jonathan Gray
> Priority: Critical
> Fix For: 0.21.0
>
> Attachments: HBASE-2694-OPENSOURCE-TRUNK-zk-based-messaging-v2.patch,
> HBASE-2694-OPENSOURCE-TRUNK-zk-based-messaging.patch
>
>
> As a first step towards HBASE-2485, this issue is about changing the message
> flow of opening and closing of regions without actually changing the
> implementation of what happens on both the Master and RegionServer sides.
> This way we can debug the messaging changes before the introduction of more
> significant changes to the master architecture and handling of regions in
> transition.
