Welcome to Bigtop!

Bigtop (http://incubator.apache.org/bigtop/) is a project for the development of packaging and tests of the Apache Hadoop (http://hadoop.apache.org/) ecosystem, currently in the Apache Incubator.

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

On Debian-based systems one also needs

• build-essential dh-make debhelper devscripts
• reprepro

On openSUSE 11.4+, in addition, one also needs to ensure the following is installed:

relaxngDatatype docbook-utils docbook-simple asciidoc fuse-devel docbook5 docbook5-xsl-stylesheets libxml2-devel xmlformat xmlto libxslt libopenssl-devel

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 (http://cloudera.github.com/bigtop/iTest) 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.*'
