Role | Definition |
Master Node1 | YARN ResourceManager, ZooKeeper, JobHistory Server, Spark History Server, Kudu master |
Master Node2 | YARN ResourceManager, ZooKeeper, Kudu master |
Master Node3 | ZooKeeper, Kudu master (All require an odd number of masters for high availability.) |
Worker nodes | NodeManager, Impalad, Kudu tablet server |
Utility nodes | Cloudera Manager, Cloudera Management Service, Hive Metastore, Impala Catalog Server, Impala StateStore, Oozie, ZooKeeper (Requires a dedicated disk), Apache Atlas, Apache Ranger |
Edge nodes | Hue, HiveServer2, Gateway configuration |
These recommendations for role assignments are intended as a starting point. Depending on the cluster size and the services that are used, the role assignments may differ. See Runtime Cluster Hosts and Role Assignments in the CDP Private Cloud Base documentation for more details.
