This site contains documentation for HPE Ezmeral Data Fabric release 6.2 including installation, configuration, administration, and reference content, as well as content for the associated bundled ecosystem components and drivers.
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.
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
This section describes how to manage the nodes and services that make up a cluster.
This section contains information related to application development for Ezmeral ecosystem components and HPE Ezmeral Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
Before you start developing applications on the HPE Ezmeral Data Fabric platform, consider how you will get the data into the platform, the storage format of the data, the type of processing or modeling that is required, and how the data will be accessed.
The following sections provide information about accessing the File Store with C and Java applications.
This section contains information about developing client applications for JSON and key-value tables.
HPE Ezmeral Data Fabric Streams brings integrated publish and subscribe messaging to HPE Ezmeral Data Fabric.
This section contains information associated with developing YARN applications.
This section describes how to leverage the capabilities of the Kubernetes Interfaces for Data Fabric.
The following sections provide information about each open-source project that is supported by the HPE Ezmeral Data Fabric.
This topic provides an overview of Apache Airflow on HPE Ezmeral Data Fabric.
This section describes the manual method for configuring security in HBase.
HBase supports MapR-SASL and Kerberos security, and can run securely independently of the security status of your HPE Ezmeral Data Fabric cluster.
HBase supports Access Control Lists (ACLs) to limit the privileges of users on the system. Before you can use ACLs, you need to perform the steps to enable ACLs.
The following steps explain how to enable HBase ACLs.
Using compression with HBase reduces the number of bytes transmitted over the network and stored on disk. These benefits often outweigh the performance cost of compressing the data on every write and uncompressing it on every read.
For HBase version 1.1 and later, a default database configuration determines whether clients connect to HBase tables or HPE Ezmeral Data Fabric Database tables. You can change the default setting for all HBase clients, or you can set the database for a particular job. This setting is ignored for HBase 0.98.12 client connections.
This section describes and shows examples of the configuration properties used in the hbase-site.xml file.

Apache Livy is primarily used to provide integration between Hue and Spark.
Describes the supported HPE Ezmeral Data Fabric Streams tools and clients.
The S3 gateway is a service that provides an S3-compatible interface to expose data in HPE Ezmeral Data Fabric as objects. The S3 gateway manages all inbound S3 API requests to put data into and get data out of cloud storage.
This section discusses topics associated with Maven and the HPE Ezmeral Data Fabric.
This section contains in-depth information for the developer.
