Ted Yu commented on HBASE-20159:
--------------------------------

I was asking about server side.
Suppose meta server was on server1. Master crashes. When backup master is 
taking over, server1 also crashes.

Thanks

> Support using separate ZK quorums for client

> Currently we are using the same zookeeper quorums for client and server, 
> which makes us under risk that if some client connection boost exhausted 
> zookeeper, RegionServer might abort due to zookeeper session loss. Actually 
> we have suffered from this many times in production.
> Here we propose to allow client to use different ZK quorums, through below 
> settings:
> {noformat}
> hbase.client.zookeeper.quorum
> hbase.client.zookeeper.property.clientPort
> hbase.client.zookeeper.observer.mode
> {noformat}
> The first two are for specifying client zookeeper properties, and the third 
> one indicating whether the client ZK nodes are in observer mode. If the 
> client ZK are not observer nodes, HMaster will take responsibility to 
> synchronize necessary meta information (such as meta location and master 
> address, etc.) from server to client ZK
