This case study-based workshop will walk attendees through every milestone of a month long effort to come up with an objective way to measure the performance of Hadoop clusters. The subject of the study was the influence of specific host operating systems and hypervisors on cluster performance.

The results identified significant deviation of cluster performance for equal workloads across various operating systems and hypervisors.

21% to 275% deviation was found between sort time of the same workloads across clusters running Ubuntu, RHEL and SmartOS.

In this panel, the Altoros and Joyent technical staff will share results of benchmarking Apache Hadoop on Ubuntu, RHEL and RedHat and Joyent hypervisors on 50-250 node clusters:

  • Benchmarking environment setup (will share Chef cookbook)
  • Configuration details
  • Anti-Patterns (things to avoid)
  • Tools used to measure cluster performance
  • How we achieved 2.75x performance improvement
  • Ideas on cost- and rule-based optimization
