Cluster Management

MapR provides high availability management and data processing services for automatic continuity throughout the cluster. You can use the MapR 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 JobTracker, management services such as the ZooKeeper, and data access services such as NFS provide continuous service during any system failure. Read the Services documentation for details.
