What’s New in Cloudera Director 2.2?

Categories: CDH Cloud Cloudera Manager Hadoop

This new release adds support for Amazon EBS volumes and the ability to diagnose cluster bootstrap errors quickly.

Cloudera Director provides a simple, reliable, enterprise-grade way to deploy, scale, and manage Apache Hadoop in the cloud of your choice. Cloudera Director enables you to deploy production-ready clusters for big data applications and successfully run workloads in the cloud.

Cloudera Director makes it easier for customers to:

  • Deploy clusters in line with patterns native to cloud infrastructure
  • Use an interface to define in one place the desired cluster specification all the way down to the operating system
  • Repeatedly and programmatically instantiate these cluster definitions
  • Adapt to the dynamic nature of cloud infrastructure

Cloudera Director 2.2 provides additional mechanisms to get that initial cluster definition right and the ability to diagnose errors and iterate quickly.
