> The attached patch improves the MRQL build process in many ways:
> 1) it now supports hadoop 0.20.x. It uses the new extra source directory
> src/main/java/MultipleInputs, which was taken from hadoop 1.x sources,
> because 0.20.x didn't support MultipleInputs.
> 2) it corrects the classpath for hadoop 2.x (yarn).
> 3) it changes the scripts bin/mrql and bin/mrql.bsp to build a single jar
> file that contains all classes. This was done because in some cases the
> hadoop/hama -libjar parameter does not work correctly in distributed mode.
> Currently, the "mvn install" builds MRQL with Hadoop 1.2.1, Hama 0.6.3, and
> Spark 0.8.1-incubating.
> To build MRQL on some other Hadoop 1.x, such as 1.0.3, use:
> mvn -Dhadoop.version=1.0.3 install
> To build MRQL on Hadoop 2.x (yarn) use:
> mvn -Pyarn -Dyarn.version=2.2.0 -Dhadoop.version=1.2.1 install
> To build MRQL on Hadoop 0.20.x use:
> mvn -PMultipleInputs -Dhadoop.version=0.20.2 install
