Thanks.
> Design procedures for ReplicationManager to notify peer change event from
> master
> ---------------------------------------------------------------------------------
>
> Key: HBASE-19397
> URL: https://issues.apache.org/jira/browse/HBASE-19397
> Project: HBase
> Issue Type: Sub-task
> Components: Replication
> Reporter: Zheng Hu
> Assignee: Zheng Hu
>
> After we store peer states / peer queues information into hbase table, RS
> can not track peer config change by adding watcher znode.
> So we need design procedures for ReplicationManager to notify peer change
> event. the replication rpc interfaces which may be implemented by
> procedures are following:
> {code}
> 1. addReplicationPeer
> 2. removeReplicationPeer
> 3. enableReplicationPeer
> 4. disableReplicationPeer
> 5. updateReplicationPeerConfig
> {code}
> BTW, our RS states will still be store in zookeeper, so when RS crash, the
> tracker which will trigger to transfer queues of crashed RS will still be a
> Zookeeper Tracker. we need NOT implement that by procedures.
> As we will release 2.0 in next weeks, and the HBASE-15867 can not be
> resolved before the release, so I'd prefer to create a new feature branch
> for HBASE-15867.
