> 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
