What is it?
Cluster-config is a command line tool that automatically optimizes the service configurations in your Cloudera cluster.
Why build it?
We needed a tool to quickly and consistently optimize CDH services to provide stable development and QA environments. We also needed a tool to help with future optimization efforts as well as help administrators debug configuration issues.
How does it work?
The tool works by running pluggable formulas written in Python. The formula is given all the cluster details; it’s up to the formula author to decide what information to use for calculations. A default formula provided with the tool primarily optimizes YARN, and Spark. New formulas can be specified on the command line.
Who should use it?
Anyone interested in optimizing CDH services.
