HPE Ezmeral Data Fabric 6.1.x is In Maintenance and transitions to "End of Maintenance" in June 2024. Please see the latest documentation.

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.
  - Architecture
    MapR Database is an enterprise-grade, high performance, NoSQL (“Not Only SQL”) database management system. You can use it to add realtime, operational analytics capabilities to big data applications. As a multi-model NoSQL database, it supports both JSON document models and key-value data models.
  - Data Models
    MapR Database can be used as both a document database and a column-oriented database. As a document database, JSON documents are stored in HPE Ezmeral Data Fabric Database JSON table. As a column-oriented database, binary files are in stored HPE Ezmeral Data Fabric Database binary tables.
  - Secondary Indexes
    Beginning with MapR 6.0, MapR Database JSON natively supports secondary indexes on fields in JSON tables. Indexes provide you with flexible, high performance access to data stored in MapR Database.
  - Change Data Capture
    The Change Data Capture (CDC) system allows you to capture changes made to data records in MapR Database tables (JSON or binary) and propagate them to a MapR Event Store For Apache Kafka topic.
  - Table Replication
    You can replicate data in one table to another table that is in the same cluster or in a separate cluster. This type of replication is in addition to the automatic replication that occurs with table regions within a volume.
    - Modes of replication
      Describes the asynchronous and synchronous modes of table replication.
    - Supported replication topologies
      Lists the primary-secondary and multi-master replication technologies.
    - Gateways for Replicating MapR Database Tables
      In MapR Database table replication, MapR Database replicates updates to tables (binary and JSON) on source MapR clusters to replicas of those tables on destination MapR clusters. Gateways are services that receive these updates and apply them to the replicas. These gateways also propagate updates from JSON tables to their secondary indexes.
    - Replica Autosetup for MapR Database Tables
      The option to automatically set up table replication, also known as replica autosetup, performs the steps to set up and start the replication of MapR Database binary table and MapR Database JSON tables. The replica autosetup option is available through the Control System and maprcli commands.
    - Table Replication States
      The replication state indicates when table replication is in progress and displays the status of operations related to replica autosetup.
    - Order of Writes at Replicas
    - Security and Replication
      Describes how to replicate data between secure clusters.
    - Licensing
      Describes the licensing requirements for MapR.
  - Gateways for Indexing MapR Database Data in Elasticsearch
    As of MapR 6.0, MapR Database Elastic Search integration capability is deprecated and no longer available in the MapR Database product.
- 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.
- 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.

Licensing

Describes the licensing requirements for MapR.

Table replication requires a license for MapR Enterprise Database Edition (M7) on source and destination clusters.
