Apache Whirr 0.7.0 has been released

Apache Whirr release 0.7.0 is now available. It includes changes covering over 50 issues, four of which were considered blockers. Whirr is a tool for quickly starting and managing clusters running on cloud services like Amazon EC2. This is the first Whirr release as a top level Apache project (previously releases were under the auspices of the Incubator). In addition to improving overall stability some of the highlights are described below:

Support for Apache Mahout as a deployable component is new in 0.7.0. Mahout is a scalable machine learning library implemented on top of Apache Hadoop.

  • WHIRR-384 – Add Mahout as a service
  • WHIRR-49 – Allow Whirr to use Chef for configuration management
  • WHIRR-258 – Add Ganglia as a service
  • WHIRR-385 – Implement support for using nodeless, masterless Puppet to provision and run scripts

Whirr 0.7.0 will be included in a scheduled update to CDH4.
