Cluster Management

Provides a synopsis of the various cluster components and their management.

Data Fabric provides high availability management and data processing services for automatic continuity throughout the cluster. You can use the Control System, command-line interface, or REST API to start, stop, and monitor services at the node or cluster level. MapReduce services such as the ResourceManager, management services such as the ZooKeeper, and data access services such as NFS provide continuous service during any system failure.

Data Fabric Monitoring (part of the Spyglass initiative) provides the ability to collect, store, and view metrics and logs for nodes, services, and jobs/applications.

This section describes the following components and services, and also describes their roles in managing a data-fabric cluster:
