  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 Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE 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 Data Fabric Database administration is associated with tables, columns and column families, and table regions.
  - Managing Tables
    HPE Data Fabric Database supports two types of table: binary tables and JSON tables. This section covers how to create, edit, and delete tables, as well as how to set parameter values, display parameter values, grant permissions and access, replicate tables, and more using the Control System and the CLI.
  - Managing Column Families and Columns
    This section covers overviews of column families in binary tables and JSON tables, how to create column families, alter them, delete them, set permissions on them, and set and display parameter values.
  - Managing Column Family Fields and Field Permissions for JSON Tables
    This sections covers details for working with column family fields. Column family fields can be added to any existing JSON table, and column families comprise optional fields.
  - Managing Table Replication
    This section contains topics about setting up table replication and administering existing replicas.
    - Preparing Clusters for Table Replication
      Preparing clusters for table replication includes configuring gateways on destination clusters, configuring the mapr-clusters.conf file on the source cluster, and, if the clusters are secure, setting up secure communications between the clusters. After you prepare the clusters for table replication, you can setup replication between tables.
    - Setting Up Table Replication Using the CLI
      You can run the maprcli table replica autosetup command to set up primary-secondary or multi-master replication from an existing source table.
    - Adding Table Replicas
      Explains how to add table replicas using either the Control System, the CLI or the REST API.
    - Displaying the List of Table Replicas
      Describes how to view information on the table replicas using the Control System or the CLI.
    - Modifying Table Replica
      Explains how to edit the properties of a replica using the Control System and the CLI.
    - Removing Table Replicas
      Explains how to un-register one or more replicas using either the Control System or the CLI.
    - Pausing Table Replication
      Explains how to pause table replication of data from a source HPE Data Fabric Database binary or JSON table to a replica HPE Data Fabric Database binary or JSON table respectively using either the Control System or the CLI.
    - Resuming Table Replication
      Explains how to resume replication between a source HPE Data Fabric Database binary or JSON table and a replica of that table when the replication state is set to paused from the Control System or by the maprcli table replica add or the maprcli table replica pause command.
    - Adding a Column Family to a Replica
      Changes to the structure of a source table are not automatically replicated to replica table. You must complete the following steps to add a column family to a replica.
    - Viewing Active Table Replication Alarms
      Describes how to view active table replication alarms using the Control System and the CLI.
    - Managing Upstream Source for Table Replicas
      - Setting Table as Upstream Source for a Replica
        Explains how to set up the current table as the upstream source for a replica if the replica was not configured to automatically re-sync with the current table.
      - Adding Upstream Source for Table
        Describes how to add an upstream source for a table using either the Control System or the CLI.
      - Listing all Upstream Sources for a Table
        Explains how to retrieve and view the list of upstream sources for a table using either the Control System, or the CLI.
      - Removing Upstream Source
        Explains how to remove a table as an upstream source using either the Control System or the CLI.
    - Addressing High Memory File Server Alarm for JSON Table Replication
      The topic describes the troubleshooting steps for memory overflow issues with JSON tables where replication has been set up, secondary indexes have been created on the JSON table being replicated, and table row size less than 1 KB.
  - Managing Secondary Indexes
    Describes how to manage secondary indexes, including adding, deleting, and listing indexes, setting up your cluster for querying, and troubleshooting index usage.
  - Administering Change Data Capture
    This topic covers the Control System and maprcli tools for managing the Change Data Capture (CDC) feature.
  - Indexing HPE Data Fabric Database Binary Tables with Elasticsearch
    As of with MapR 6.0, HPE Data Fabric Database Elastic Search integration capability is deprecated and no longer available in the HPE Data Fabric Database product.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Data Fabric gateway mediates one-way communication between a source HPE Data Fabric cluster and a destination cluster. You can replicate HPE Data Fabric Database tables (binary and JSON) and HPE Data Fabric Streams streams. HPE 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 security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use Data Fabric clusters securely.

Setting Table as Upstream Source for a Replica

Explains how to set up the current table as the upstream source for a replica if the replica was not configured to automatically re-sync with the current table.

Setting Up Current Table as Upstream Source for a Replica Using the Control System

About this task

To set up a table as the upstream source for replicas:

Procedure

Go to the Replication tab in the table information page.
Select the checkbox beside the replicas that do not have the current table configured as upstream source for automatic re-sync.
Selecting a checkbox next to a replica makes the Actions drop-down menu available.
Select Set Current Table as Upstream Source from the Actions drop-down menu.
The Set Current Table as Upstream Source dialog displays.
Review the list of selected replicas and click Set Upstream Source.
The current table will automatically send updates to the replica(s).

Setting Up Table as Upstream Source for a Replica Using the CLI or REST API

About this task

The basic command to set a table as the upstream source for a replica is:

maprcli table upstream add -path <replica table path> -upstream <source table path>

See table upstream add for complete reference information.
