M3 provides a subset of the features available in MapR's M5 and M7 editions to enable new users to get started with Hadoop in a fast and secure manner. M3 provides direct data ingestion via NFS, eliminating the need for building separate clusters just for data ingestion and allowing existing applications, libraries and tools to work on Hadoop. M3 also supports MapR Distribution's volume-based data and user management to provide a secure multi-tenant environment for different users to use Hadoop on the same cluster.M3 also comes with a free, yet advanced management and monitoring console that provides cluster heat-map, alerts, alarms and scores of granular job and task diagnostic tools.
