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.
7.9.0 Development
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.
- Application Development Process
  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.
- File Store and Apps
  The following sections provide information about accessing the File Store with C and Java applications.
- HPE Ezmeral Data Fabric Database and Apps
  This section contains information about developing client applications for JSON and key-value tables.
- Apache Kafka Wire Protocol Service
  HPE Ezmeral Data Fabric Streams supports Apache Kafka Wire Protocol Service. Apache Kafka Wire Protocol Service is a TCP/IP service that emulates a Kafka cluster backed by HPE Ezmeral Data Fabric Streams. The service makes it possible for Apache Kafka clients written in any programming language to access topics in HPE Ezmeral Data Fabric Streams.
- HPE Ezmeral Data Fabric Streams and Apps
  HPE Ezmeral Data Fabric Streams brings integrated publish and subscribe messaging to HPE Ezmeral Data Fabric.
- MapReduce and Apps
  This section contains information associated with developing YARN applications.
- Kubernetes Interfaces for Data Fabric
  This section describes how to leverage the capabilities of the Kubernetes Interfaces for Data Fabric.
- Ecosystem Components
  The following sections provide information about each open-source project that is supported by the HPE Ezmeral Data Fabric.
  - Ecosystem Packs
  - Apache Airflow
    This topic provides an overview of Apache Airflow on HPE Ezmeral Data Fabric.
  - AsyncHBase
    - Configuring the Default Database for AsyncHBase
      For AsynchHBase 1.7 and later, you can configure whether AsyncHBase accesses HBase tables or MapR-DB tables by default. If this value is not configured, AsyncHBase will determine the table type.
    - Compiling and Running AsyncHBase Applications
      When you compile or run AsyncHBase applications, you need to include the required AsyncHBase libraries.
    - AsyncHBase Script
      Data Fabric provides an AsyncHBase script that you can use to run applications and generate the AsyncHBase classpath.
    - AsyncHBase Behavior with HPE Ezmeral Data Fabric Database Binary Tables
      After you install AsyncHBase, you can use the AsyncHBase libraries to provide asynchronous access to HPE Ezmeral Data Fabric Database binary tables. However, it is important to note the behavior that is specific to using AsyncHBase with HPE Ezmeral Data Fabric Database.
    - Using OpenTSDB with AsyncHBase
      OpenTSDB can use Data Fabric’s AsyncHBase to perform time-series data-plots on HPE Ezmeral Data Fabric Database binary tables.
    - GetRequest API
      MapR includes an additional constructor for the GetRequest class which takes an extra qualifier.
  - Cascading
  - Apache Drill
  - Hadoop
  - HBase
  - HBase Client and HPE Ezmeral Data Fabric Database Binary Tables
  - HCatalog
  - Hive
  - HttpFS
  - Hue
  - Livy
    Apache Livy is primarily used to provide integration between Hue and Spark.
  - HPE Ezmeral Data Fabric Streams Clients and Tools
    Describes the supported HPE Ezmeral Data Fabric Streams tools and clients.
  - NiFi
    This topic provides an overview of Apache NiFi on HPE Ezmeral Data Fabric.
  - OTel
    This topic provides an overview of OpenTelemetry on HPE Ezmeral Data Fabric.
  - Ranger
  - Apache Spark
  - YARN
  - Zeppelin
- Maven and the HPE Ezmeral Data Fabric
  This section discusses topics associated with Maven and the HPE Ezmeral Data Fabric.
- Developer's Reference
  This section contains in-depth information for the developer.
- API Documentation
  HPE Ezmeral Data Fabric supports public APIs for file system, HPE Ezmeral Data Fabric Database, and HPE Ezmeral Data Fabric Streams. These APIs are available for application-development purposes.
Other Docs

Glossary
Definitions for commonly used terms in MapR Converged Data Platform environments.

AsyncHBase

Data Fabric provides a version of AsyncHBase that is modified to work with HPE Ezmeral Data Fabric Database binary tables. The Data Fabric version of AsyncHBase is based on the AsyncHBase library provides asynchronous Java APIs to access HPE Ezmeral Data Fabric Database binary tables. The HBase Client version is based on the current EEP and Data Fabric version you are running. For more information, see the Interoperability Matrices.
