java.lang.Object
- ml.shifu.guagua.master.BasicMasterInterceptor<MASTER_RESULT,WORKER_RESULT>
- - ml.shifu.guagua.hadoop.ZooKeeperMasterInterceptor<MASTER_RESULT,WORKER_RESULT>

All Implemented Interfaces:

ml.shifu.guagua.master.MasterInterceptor<MASTER_RESULT,WORKER_RESULT>
```
public class ZooKeeperMasterInterceptor<MASTER_RESULT extends ml.shifu.guagua.io.Bytable,WORKER_RESULT extends ml.shifu.guagua.io.Bytable>
extends ml.shifu.guagua.master.BasicMasterInterceptor<MASTER_RESULT,WORKER_RESULT>
```
To start zookeeper instance in cluster environment.
Compare with start zookeeper instance in client process, ZooKeeperMasterInterceptor can be used in cluster and even to start zookeeper ensemble in cluster to void single point failure issue.
