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 ## 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.*' ## Contact us!
