HPE Ezmeral Data Fabric 6.2 Documentation

6.2 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Administering Users and Clusters
  Lists topics that help manage a data-fabric cluster.
- Administering Nodes
  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Ezmeral Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Ezmeral Data Fabric gateway mediates one-way communication between a source HPE Ezmeral Data Fabric cluster and a destination cluster. You can replicate HPE Ezmeral Data Fabric Database tables (binary and JSON) and HPE Ezmeral Data Fabric Event Data Streams streams. HPE Ezmeral Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure MapR security and manage secure clusters.
  - 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.
    - Getting Started with HPE Ezmeral Data Fabric Security
      Describes quick implementation of security.
    - Managing Encryption for MapR Core
      Provides information that allows you to use encryption across the MapR platform.
    - Determining if a Cluster is Secure and Enabled for Encryption
      Explains how to use the Control System, the CLI, and the REST API to determine whether or not a cluster is secure and whether or not on-wire encryption and data at rest encryption are enabled at the cluster and volume levels.
    - Configuring Authentication
      Provides information about MapR ticket, Kerberos, Pluggable Authentication Module (PAM) authentication.
    - Managing Access Controls
      Describes how to create, enable, and use ACLs and ACEs.
      - Managing Access Control Lists
        Defines and describes how to create ACLs.
        Creating Cluster-level ACLs
        Creating Job Queue ACLs
        Creating Volume-level ACLs
      - Managing Access Control Expressions
        Defines and describes how to create, enable, and use ACEs.
      - Creating Subnet Whitelists
        Provides the procedure necessary to restrict access to cluster data.
    - Configuring Policy-Based Security
      Starting in HPE Ezmeral Data Fabric 6.2.0 (MEP 7.0.0), HPE Ezmeral Data Fabric supports Policy-Based Security. Policy-Based Security is a mechanism that enables administrators to create security policies for simplified data management. Administrative users can create and manage security policies through the control system, maprcli, REST API, Hadoop and Linux commands, and Java APIs.
    - Customizing Security in HPE Ezmeral Data Fabric
      Describes the .customSecure file and how HPE Ezmeral Data Fabric 6.x handles custom security settings.
  - Managing Impersonation
    Provides instructions for enabling and using MapR impersonation features.
- Managing Secure Clusters
  Provides procedures that will enable you to use MapR clusters securely.
- Administering the Data Access Gateway
  The HPE Ezmeral Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Ezmeral Data Fabric cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.
- Best Practices for Backing Up HPE Ezmeral Data Fabric Information
  Lists the best practices and performance considerations to follow when backing up HPE Ezmeral Data Fabric information.

Managing Access Control Lists

Defines and describes how to create ACLs.

An access control list (ACL) specifies users or system processes that can perform specific actions on an object.
