Using Multiple ZooKeeper Services
Cloudera Manager requires dependent services within CDH to use the same ZooKeeper service. If you configure dependent CDH services to use different ZooKeeper services, Cloudera Manager reports the following error:
com.cloudera.cmf.command.CmdExecException:java.lang.RuntimeException: java.lang.IllegalStateException: Assumption violated: getAllDependencies returned multiple distinct services of the same type at SeqFlowCmd.java line 120 in com.cloudera.cmf.command.flow.SeqFlowCmd run()
CDH services that are not dependent can use different ZooKeeper services. For example, Kafka does not depend on any services other than ZooKeeper. You might have one ZooKeeper service for Kafka, and one ZooKeeper service for the rest of your CDH services.
