About MapR 6.1
This site contains the main documentation for Version 6.1 of the MapR Converged Data Platform, including installation, configuration, administration, and reference information.
6.1 Installation
This section contains information about installing and upgrading MapR software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
6.1 MapR Data Platform
MapR Data Platform is the industry-leading data platform for AI and analytics that solves enterprise business needs.
- MapR XD Distributed File and Object Store
  MapR XD Distributed File and Object Store is a distributed file system for data storage, data management, and data protection. MapR XD supports mounting and cluster access via NFS and FUSE-based POSIX clients (basic, platinum, or PACC) and also supports access and management via HDFS APIs.
- MapR Database
  MapR Database is an enterprise-grade, high-performance, NoSQL database management system that you can use for real-time, operational analytics.
- MapR Event Store For Apache Kafka
  MapR Event Store For Apache Kafka brings integrated publish and subscribe messaging to the MapR Converged Data Platform.
- MapR Data Fabric for Kubernetes
  This section describes the MapR Data Fabric for Kubernetes, which include the Container Storage Interface (CSI) driver for multiple container-orchestration systems, and the FlexVolume driver for Kubernetes.
- Cluster Management
  Provides a synopsis of the various cluster components and their management.
- Security
  Provides an overview of the MapR security features.
  - Authentication in MapR
    Describes types of authentication available with the MapR Data Platform and how to manage user authentication with the maprlogin utility.
  - Authorization in MapR
    Describes the basics of authorization including Access Control Lists and Access Control Expressions.
  - Encryption in MapR
    Describes encryption types available on the MapR Data Platform.
    - SSL Certificates
      Describes how certificates are used to perform authentication and encryption for websites that use the HTTPS protocol.
    - Security Protocols Used by MapR
      Lists the various security protocols that MapR uses for encryption and authentication.
    - HTTPS Excluded Ciphers
      Lists the weak ciphers that are excluded from the MapR HTTPS implementation.
    - TLS 1.2 Supported Ciphers
      Lists the ciphers that are supported (and not supported) by MapR Data Platform for use with TLS 1.2.
  - Impersonation in MapR
    Describes impersonation in MapR, which allows centralized control of access to resources in the MapR File System, MapR Database, and MapR Event Store For Apache Kafka.
  - Auditing in MapR
    MapR allows you to log audit records of cluster-administration operations, and operations on directories, files, streams and tables.
  - Security for Ecosystem Components
    Whether you install MapR software by using the MapR Installer or by using manual steps, the platform and its ecosystem components are installed with security ON by default.
  - Security Settings for Ecosystem Components
    Lists the security settings for all MapR ecosystem components.
  - Security Exceptions
    "Secure by default" means network-safe authentication and encryption. This page describes areas in which secure-by-default capabilities are not yet implemented for the MapR platform or ecosystem components. Included where applicable, are links to more information to help you work around those issues.
- YARN
- Client Connections
  The following sections describe how a client connects to local and remote MapR clusters.
6.1 Administration
This section describes how to manage the nodes and services that make up a cluster.
6.1 Development
This section contains information related to application development for Ezmeral ecosystem components and MapR Data Platform products, including the file system, Database (Key-Value and JSON), and Event Streams.
Other Docs
This section contains release-independent information, including: MapR Installer documentation, Ecosystem release notes, interoperability matrices, security vulnerabilities, and links to other MapR version documentation.
Glossary
Definitions for commonly used terms in MapR Converged Data Platform environments.

Security Protocols Used by MapR

Lists the various security protocols that MapR uses for encryption and authentication.

Protocol	Encryption	Authentication
MapR RPC	AES/GCM	maprticket
Hadoop RPC and MAPRSASL	AES/GCM	maprticket
Hadoop RPC and Kerberos	Kerberos	Kerberos ticket
Generic HTTP Handler	HTTPS using SSL/TLS	maprticket, username and password, or Kerberos SPNEGO
