About Release 7.9.0
This site contains documentation for HPE Ezmeral Data Fabric release 7.9.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
7.9.0 Installation
This section contains information about installing and upgrading HPE Ezmeral Data Fabric software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a HPE Ezmeral Data Fabric cluster.
7.9.0 Data Fabric
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
7.9.0 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 Managed 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.
  - Managing Tables
    HPE Ezmeral 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.
    - Creating Column Families
      Explains how to create column families using either the Control System, the CLI, or the HBase shell.
      - Permission Types for Fields and Column Families in JSON Tables
        By using ACEs, you can grant or deny access to fields and column families that are in JSON tables.
        Obtaining readperm and writeperm on Fields
        In this scenario, you want to perform an operation on a field, and the operation requires that you have readperm and writeperm permissions on that field. How you obtain these permissions depends on whether the field is in the default column family or a non-default column family.
        Obtaining readperm or writeperm on Fields
        In this scenario, you want to perform an operation on a field, and the operation requires that you have readperm or writeperm permissions on that field. How you obtain either permission depends on whether the field is in the default column family or a non-default column family.
        Setting Permissions on Arrays
        If you are granting permissions on a field and the field contains array data, you must grant the permission on the array field. This grants access not only to array data in the field, but also nested documents and scalar data. It is also possible to set permissions on subfields within nested documents that are stored in an array.
        Granting Permissions on JSON Tables
        Summarizes the default ACEs for the supported ways of setting read, traverse, and write permissions.
    - Listing Column Families
      Explains how to view the column families for a table using either the Control System or the CLI.
    - Removing Column Families
      Explains how to delete column families using either the Control System or the CLI.
    - Altering Column Families
      Explains how to modify the permissions and properties of column families using either the Control System, the CLI, or the HBase shell.
    - Displaying Default Column Family Permissions
      Use either the Control System or the maprcli command to find out the users, groups, or roles that have permissions on the default column family.
  - 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.
  - 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 Ezmeral Data Fabric Database Binary Tables with Elasticsearch
    As of with MapR 6.0, HPE Ezmeral Data Fabric Database Elastic Search integration capability is deprecated and no longer available in the HPE Ezmeral Data Fabric Database product.
- 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 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 security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use Data Fabric 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.
- IPv6 Support in Data Fabric
  Describes the IPv6 support feature for Data Fabric.
7.9.0 Development

Granting Permissions on JSON Tables

Summarizes the default ACEs for the supported ways of setting read, traverse, and write permissions.

The default permissions for column families are determined when tables are created. The default permissions for fields are inherited from the column family where the fields are located.

Action	Method	Permissions	Default Access-Control Expressions
Set default permissions on new column families when creating a JSON table.	Java API	`-defaultreadperm -defaulttraverseperm -defaultwriteperm`	`u:<ID of the process>`
	`maprcli table create`		`u:<user ID of table creator>`
	mapr dbshell
	Control System
Set default permissions on new column families when editing a JSON table.	`maprcli table edit`		Current ACEs
	Control System		Current ACEs
Set permissions on a column family when creating the column family.	`maprcli table cf create`	`-readperm -traverseperm -writeperm -indexperm`	ACEs for `‑defaultreadperm`, `‑defaulttraverseperm`, and `‑defaultwriteperm`
	Control System
Set permissions on a column family when editing the column family.	`maprcli table cf edit`		Current ACEs
	Control System		Current ACEs
Set permissions on individual fields.	`maprcli table cf colperm set`		Inherited from column family or parent field
Set permissions on individual fields.	Control System		Inherited from column family or parent field
Set the dynamic mask	`maprcli table cf column datamask set`	`-defaultunmaskedreadperm -unmaskedreadperm`	Set to the table creator
	`maprcli table cf colperm set`
	`maprcli table create`
	`maprcli table edit`
	`maprcli table cf create`
