The following node architecture depicts the CDP Private Cloud Base high-level architecture.
The cluster environment consists of multiple software services running on multiple physical server nodes.
The implementation divides the server nodes into several roles, and each node has a configuration that is optimized for its role in the cluster. The physical server configurations are divided into two broad classes:
The high-performance network fabric connects the cluster nodes together and separates the core data network from management functions.
The minimum supported configuration is eight cluster nodes, which include three master nodes, one utility node, one edge node, and three worker nodes. Starting with a ten-node cluster with five worker nodes is a common practice. The nodes have the roles that are described in cluster node roles.
Note: All nodes roles listed below are required.
Hardware configuration | |
Master nodes | Infrastructure |
Utility nodes | Infrastructure |
Edge nodes | Infrastructure |
Worker nodes | Worker |
The following node definitions define the various nodes.
Role | Definition |
Master nodes | Runs all the daemons that are required to manage the cluster storage and compute services |
Worker nodes | Runs all the services that are required to store blocks of data on the local hard drives and run processing tasks against that data |
Utility nodes | Runs Cloudera Manager and the Cloudera Management Services |
Edge nodes | Contains all client-facing configurations and services, including gateway configurations |
