Welcome to Bigtop!

Bigtop is a project for the development of packaging and tests of the Apache Hadoop ecosystem.

The primary goal of Bigtop is to build a community around the packaging and interoperability testing of Hadoop-related projects. This includes testing at various levels (packaging, platform, runtime, upgrade, etc...) developed by a community with a focus on the system as a whole, rather than individual projects.

Building Bigtop

Packages have been built on Ubuntu 10.10, CentOS 5 and openSUSE 11.4. They can probably be built on other platforms as well.

Building Bigtop requires the following tools:

  • Java JDK 1.6
  • Apache Forrest 0.8 (requires 32bit version of Java JDK 1.5)
  • Apache Ant
  • Apache Maven
  • git
  • subversion
  • autoconf
  • automake
  • liblzo2-dev
  • libz-dev
  • sharutils
  • libfuse-dev
  • libssl-dev

On Debian-based systems one also needs

  • build-essential dh-make debhelper devscripts
  • reprepro

Building packages

$ make [component-name]-[rpm|deb]

Building local YUM/APT repositories

$ make [component-name]-[yum|apt]

Running the tests

WARNING: since testing packages requires installing them on a live system it is highly recommended to use VMs for that.

Testing Bigtop is done using iTest framework. For more documentation on iTest visit the iTest page but here's 2 steps to get started:

  • install package testing iTest artifacts locally:

    cd test/src/smokes/package/ && mvn install -DskipTests -DskipITs -DperformRelease

  • use those locally installed iTest package testing artifacts to run a suite:

    cd test/suites/package/ && mvn clean verify -Dcdh.repo.file.url.CentOS=XXX -D'org.apache.maven-failsafe-plugin.testInclude=**/TestPackagesReadiness.*'
