> Minor improvement to HBaseTest example, when Hbase related configurations e.g: zookeeper quorum, zookeeper client port or zookeeper.znode.parent are not set to default (localhost:2181), connection to zookeeper might hang as shown in following stack
> 15/03/26 18:31:20 INFO zookeeper.ZooKeeper: Initiating client connection, connectString=xxx.xxx.xxx:2181 sessionTimeout=90000 watcher=hconnection-0x322a4437, quorum=xxx.xxx.xxx:2181, baseZNode=/hbase
> 15/03/26 18:31:21 INFO zookeeper.ClientCnxn: Opening socket connection to server 9.30.94.121:2181. Will not attempt to authenticate using SASL (unknown error)
> 15/03/26 18:31:21 INFO zookeeper.ClientCnxn: Socket connection established to xxx.xxx.xxx/9.30.94.121:2181, initiating session
> 15/03/26 18:31:21 INFO zookeeper.ClientCnxn: Session establishment complete on server xxx.xxx.xxx/9.30.94.121:2181, sessionid = 0x14c53cd311e004b, negotiated timeout = 40000
> 15/03/26 18:31:21 INFO client.ZooKeeperRegistry: ClusterId read in ZooKeeper is null
> this is due to hbase-site.xml is not placed on spark class path.
