Spark QA Infrastructure Overview

Spark's Jenkins CI and QA infrastructure is hosted by UC Berkeley's AMPLab.  The machines live in the IS&T datacenter.  We have one Jenkins master, and currently eight Jenkins worker nodes.

Jenkins Worker Configuration

The following list of software packages are installed on each worker node, and required to build the myriad variations of spark:

• Java JDK 7u71
• git
• Python and python packages:

• python (2.6 default, 2.7)

• python-pip

• pypy

• numpy

• scipy

• python-matplotlib

• python-nose

• sympy

• python-pandas

• ipython

• unittest2

• numpy

• R and friends:
  • R
  • rJava
  • testthat
  • digest
• Maven 3.1.1 (default)
• Maven 3.0.5
• SBT
