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.
    - Getting Started with MapR Security
      Describes two core scenarios that allow quick implementation of security features.
    - Managing Encryption for MapR Core
      Provides information that allows you to use encryption across the MapR platform.
    - Authenticating Users
      Provides information about MapR ticket, Kerberos, Pluggable Authentication Module (PAM) authentication.
      - Tickets
        Introduces authenticate using tickets for users and MapR servers.
        How Tickets Work
        Describes how tickets enable secure communication between the client and the server.
        Generating a MapR User Ticket
        Describes how to generate a user ticket and use it in a typical work flow.
        Generating a Service Ticket
        Describes how to use a service ticket to run services outside the cluster.
        Generating a Service with Impersonation Ticket
        Describes how to generate and manage impersonation tickets.
        Generating a MapR Ticket from a Kerberos Ticket
        Provides instructions on how to use a Kerberos ticket to generate a MapR ticket.

Tickets

Introduces authenticate using tickets for users and MapR servers.

MapR implements authentication with tickets. Tickets contain keys, and are used to authenticate users and MapR servers. In addition, certificates are used to implement server authentication. Every user who wants to access a cluster must have a MapR user ticket (maprticket_<uid>) and every node in the cluster must have a MapR server ticket (maprserverticket).

A ticket is an object that contains specific information about a user and a key. A ticket authenticates a user to the cluster. Tickets are encrypted to protect their contents. MapR supports three types of tickets that can be used for authentication:

MapR user tickets
MapR service tickets
Kerberos tickets

IMPORTANT: The identity of the user that authenticates with the maprlogin utility is independent from the identity of the user of the client OS.

MapR tickets contain the following information:

UID (generated from the UNIX user ID)
GIDs (group IDs for each group the user belongs to)
ticket creation time
ticket expiration time (initial duration of the ticket)
renewal expiration time (maximum lifetime of the ticket)
Whether user can (true) or cannot (false) impersonate another user

Note that, because a ticket contains the GIDs for a user at the time the ticket is generated, a user must re-generate their ticket after changing group memberships.

For complete syntax, see The maprlogin Utility.
