| # Welcome to Bigtop! |
| |
| 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 all of Bigtop requires the following tools: |
| |
| * Java JDK 1.6 |
| * Apache Forrest 0.8 |
| * 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. The tests are organized in maven submodules, with |
| one submodule per bigtop component. |
| |
| The bigtop-tests/test-execution/smokes/pom.xml defines all submodules to be tested, and |
| each submodule is in its own directory under smokes/, for example: |
| |
| smokes/hadoop/pom.xml |
| smokes/hive/pom.xml |
| ... and so on. |
| |
| For more documentation on iTest and testing visit Bigtop wiki http://bigtop.apache.org/, |
| but here's 2 steps to get started: |
| |
| ## Running the tests: Installing smoke tests |
| * To install your iTest test jars locally (i.e. package/hadoop/flume/sqoop/...) |
| |
| #Note: the --offline option should be used, after you have all dependencies, so that you don't |
| #overwrite your built snapshots with remote snapshots. |
| mvn install -DskipTests -DskipITs -DperformRelease -f bigtop-tests/test-execution/smokes/package/pom.xml |
| |
| ## Running the tests: Running the installed smoke test jars on your cluster |
| |
| * Example 1: To run the iTest testing suite for the "packaging" submodule (i.e. package/hadoop/flume/sqoop/...) |
| |
| mvn clean verify -Dbigtop.repo.file.url.CentOS=XXX -D'org.apache.maven-failsafe-plugin.testInclude=**/TestPackagesReadiness.*' -f bigtop-tests/test-execution/smokes/package/pom.xml |
| |
| |
| * Example 2: Running the mapreduce standard smokes - for the "hadoop" submodule, further specifying only those in the hadoop examples jar (like WordCount, Calculate PI, and so on): |
| |
| mvn clean verify -Dbigtop.repo.file.url.CentOS=XXX -D'org.apache.maven-failsafe-plugin.testInclude=**/*TestHadoopExamples*' -f bigtop-tests/test-execution/smokes/package/pom.xml |
| |
| Note: A minor bug/issue is that you need the testInclude regular expression above is needed even if you want to run all tests, because iTest names don't follow the maven integration test naming convention of IT*, but instead, follow the surefire (unit test) convention of Test*. |
