The ZooKeeper service is enabled in E-MapReduce clusters by default.

Note ZooKeeper only has 3 nodes, regardless of how many machines are currently in the cluster. More nodes are not currently supported.

Create a cluster

When you create a cluster, select the Zookeeper service in the software configuration page.

Node information

After you have created a cluster and its status is idle, in the Clusters and Services page, select ZooKeeper, and then click Component Topology to view ZooKeeper nodes. E-MapReduce enables 3 ZooKeeper nodes. The corresponding intranet IP address (2181 is the default port) of ZooKeeper nodes are indicated in the IP column for access to the ZooKeeper service.
