Bigtop (http://bigtop.apache.org/) is a project for the development of packaging and tests of the Apache Hadoop (http://hadoop.apache.org/) 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 for CentOS/RHEL 5 and 6, Fedora 17, SuSE Linux Enterprise 11, OpenSUSE12.2, Ubuntu LTS Lucid and Precise, and Ubuntu Quantal. They can probably be built for other platforms as well.Some of the binary artifacts might be compatible with other closely related distributions. 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 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 and testing visit Bigtop wiki http://bigtop.apache.org/, 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 -Dbigtop.repo.file.url.CentOS=XXX -D'org.apache.maven-failsafe-plugin.testInclude=**/TestPackagesReadiness.*' * to run all smoke tests on the cluster export HADOOP_HOME; HADOOP_CONF_DIR; HADOOP_MAPRED_HOME; HBASE_HOME; HIVE_HOME; HUE_URL; OOZIE_URL; SOLR_URL; SQOOP_URL then run mvn -fae clean verify -Dorg.apache.bigtop.itest.log4j.level=TRACE -f bigtop-tests/test-execution/smokes/pom.xml -fae - will allow all non-impacted builds to continue, so you can run all the tests and deal with the error reports later -Dorg.apache.bigtop.itest.log4j.level can be set to your liking. ## Contact us!
