Thanks very much. And I have another question. The hbase books said: If you can, upgrade your zookeeper. If you can’t, 3.4.2 clients should work against 3.3.X ensembles (HBase makes use of 3.4.2 API). As I know, zookeeper 3.4.2 is not a stable version. So I can't upgrade hbase cluster to version 0.92? Can hbase 0.92 and zookeeper 3.3 work well?
