- MapR System Overview
  MapR is a complete enterprise-grade distribution for Apache Hadoop. The MapR Converged Data Platform has been engineered to improve Hadoop’s reliability, performance, and ease of use.
  - MapR-XD
  - Cluster Management and Monitoring
  - MapR-DB Overview
    MapR-DB is an enterprise-grade, high-performance, NoSQL database management system. You can use it for real-time, operational analytics capabilities.
  - MapR Streams Overview
    MapR Streams brings integrated publish/subscribe messaging to the MapR Converged Data Platform.
  - Security Overview
    - Security Capabilities
      This section describes authentication, authorization, and encryption capabilities. A secure MapR environment is predicated on authentication, authorization, and encryption capabilities.
      - Authentication in MapR
        Robust MapR authentication prevents third parties from representing themselves as legitimate users.
      - Authorization in MapR
        Authorization restricts an authenticated MapR user's capabilities on the system. Flexible authorization systems enable a system to grant a user a set of capabilities that enable the user to perform desired tasks, but prevents the use of any capabilities outside of that scope.
      - Encryption in MapR
        Encryption in a MapR system restricts an external party's ability to read or modify data.
      - Impersonation in MapR
        Impersonation in MapR allows centralized control of access to resources in the MapR-FS, MapR-DB, and HBase systems.
      - Auditing in MapR
        Auditing features in MapR let you log audit records of cluster-administration operations and operations on directories, files, and tables.
    - Security Architecture
      The design of the MapR security architecture takes into account the main threats to a secure cluster. By default, MapR provides basic authorization functionality and some authentication.
    - Ports Used for Secure Services
      This section lists the ports used by web interfaces for secure Hadoop 2 services
  - MapReduce Version 1
  - YARN
- MapR Sandbox for Hadoop
  The MapR Sandbox for Hadoop is a fully-functional single-node cluster that gently introduces business analysts, current and aspiring Hadoop developers, and administrators (database, system, and Hadoop) to the big data promises of Hadoop and its ecosystem.

- Version 5.2.1 Release Notes
  5.2.1 is the latest maintenance release of the MapR Converged Data Platform 5.2. These notes list the differences between 5.2.1 and 5.2.0. Use these when you install 5.2.1 or upgrade to 5.2.1.
- Version 5.2 Release Notes
  These release notes contain information about Version 5.2 of the MapR Converged Data Platform.

Security Capabilities

This section describes authentication, authorization, and encryption capabilities. A secure MapR environment is predicated on authentication, authorization, and encryption capabilities.

Authentication: Restricting access to a specified set of users. Robust authentication prevents third parties from representing themselves as legitimate users.
Authorization: Restricting an authenticated user's capabilities on the system. Flexible authorization systems enable a system to grant a user a set of capabilities that enable the user to perform desired tasks, but prevents the use of any capabilities outside of that scope.
Encryption: Restricting an external party's ability to read data. Data transmission between nodes in a secure MapR cluster is encrypted, preventing an attacker with access to that communication from gaining information about the transmission's contents.
