Red Hat Training

A Red Hat training course is available for Red Hat OpenStack Platform

2.12. OpenStack Data Processing Service

This section outlines the top new features for the OpenStack Data Processing (sahara) service.
OpenStack Data Processing Service Integration With Baremetal to Tenant
The OpenStack Data Processing service can help improve performance by removing the hypervisor abstraction layer. The OpenStack Bare Metal Provisioning (ironic) service provides an API and a Compute driver to serve bare metal instances using the same Compute and OpenStack Networking APIs.
This release adds the support to install and configure the OpenStack Bare Metal Provisioning service and Compute to serve the bare metal instance to the tenant. For Red Hat OpenStack Platform deployments with both virtual and bare metal instances, you need to use host aggregates as follows:
  • One for all the bare metal hosts
  • One for all the virtual Compute nodes
Support for the Cloudera Distribution of Apache Hadoop (CDH) 5.11
You can deploy the Cloudera Distribution of Apache Hadoop (CDH) 5.11 on Red Hat OpenStack Platform. CDH can store, process, and analyze large and diverse data volumes with the latest big data processing techniques such as Spark and Impala.
