When a master cluster RS initiates a replication source to a slave cluster, it first connects to the slave's ZooKeeper ensemble using the provided cluster key (that key is composed of the value of, and ientPort). In the command window I start HBase. StatefulSet specifies a liveness probe. ZooKeeper ensures this by using the Zab consensus protocol to replicate a state machine across all servers in the ensemble. Data are organized in a file system like hierarchy and replicated to all ZooKeeper servers in the ensemble (a set of ZooKeeper servers). Enter a valid email to continue.
