             Summary: Use P2P communicate between region servers to sync the 
list for bootstrap node
                 Key: HBASE-26220
                 URL: https://issues.apache.org/jira/browse/HBASE-26220
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang


For returning bootstrap nodes to client, we do not need to always track exactly 
the current live region server. But now, we just set a watcher on zookeeper to 
watch all the live region servers, on every region server, for large cluster, 
it will be a big pressure for zookeeper.

So here I think, we could let region servers to communicate with each other to 
sync the available bootstrap node, like a P2P network.

Will put a simple design doc soon.
