MapR 5.2 Documentation

5.2 Cluster Administration
This section contains information on administering the cluster and MapR-DB, configuring Gateways, and configuring and managing particular aspects of the MapR security infrastructure.
- Administering the Cluster
  This section describes how to manage the nodes and services that make up a cluster.
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring and Managing MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. MapR-DB tables and MapR Streams streams can be replicated.
- Administering MapR-DB
  Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families, and table regions.
- Configuring Security
  Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.
  - Configuring Mapr Security
    Provides usage information for frequently used security functionality including Access Control Lists (ACLs), Access Control Expressions (ACEs), file permissions, and subnet whitelisting.
  - Managing Secure Clusters
    Provides procedures that will enable you to run use MapR clusters securely.
    - Running Commands on Remote Secure Clusters
      Explains how to manage two secure clusters from a single secure cluster.
    - Adding Cross-Cluster Tickets to Secure Clusters
      Introduces the cross-cluster ticket generation process on a secure cluster.
    - Managing Mirror Volumes in Secure Clusters
      Describes how to secure the cluster mirror user and blacklist mirror users.
    - Managing TaskTracker Users
      Provides guidance required to work with users who submit TaskTracker jobs.
    - Managing Permissions
      Lists API user permission requirements and describes how to set file-level permissions for objects in the MapR-FS layer.
    - Accessing External HDFS Clusters
      Outlines how to use HDFS protocols to connect to other clusters.
    - Using Java Applications with Secure Clusters
      Describes ramifications associated with using Java applications in a MapR secure environment.
  - Managing Auditing
    Provides instructions for using MapR auditing features.
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Glossary
  This section contains defintions for commonly used terms in MapR Converged Data Platform environments.

Managing Secure Clusters

Provides procedures that will enable you to run use MapR clusters securely.

Administrative topics such as managing users, permissions, volumes in secure cluster are discussed. In addition, access scenarios for secure and non-secure MapR clusters and HDFS clusters are described.
