The following page has been changed by CorinneC: http://wiki.apache.org/pig/GettingStarted ------------------------------------------------------------------------------ == Requirements == - 1. '''Java 1.5''' or newer, preferably from Sun. Set JAVA_HOME to the root of your Java installation. + 1. '''Java 1.5.x''' or newer, preferably from Sun. Set JAVA_HOME to the root of your Java installation. 2. '''Ant''' build tool: [http://ant.apache.org/]. 3. To run unit tests, you also need '''JUnit''': [http://junit.sourceforge.net/]. 4. To run pig programs, you need access to a '''Hadoop cluster''': [http://lucene.apache.org/hadoop/]. It's also possible to run pig in "local" mode, with severely limited performance - this mode doesn't require setting up a Hadoop cluster. == Building Pig == - [Jeff] This needs to be changed, since 0.15 clusters are not supported any longer - 1. Check out pig code from svn: `svn co http://svn.apache.org/repos/asf/incubator/pig/trunk`. 2. Build the code from the top directory: `ant`. If the build is successful, you should see `pig.jar` created in that directory. - 3. If you need to interact with a hadoop 0.15.x cluster, run ant clean; ant -Dhadoop.jarfile=hadoop15.jar to rebuild with the 15 hadoop code. The clean is needed when switching hadoop versions + 3. To validate your `pig.jar` run unit test: `ant test` + == Running Pig Programs ==
