It will currently not work with 2.8, or with +earlier versions of the 2.7 branch. + +To build and run Spark, you will need to have Scala's bin in your $PATH, +or you will need to set the SCALA_HOME environment variable to point +to where you've installed Scala. Scala must be accessible through one +of these methods on Nexus slave nodes as well as on the master. + +To build Spark and the example programs, run make. + +To run one of the examples, use ./run <class> <params>. For example, +./run SparkLR will run the Logistic Regression example. Each of the +example programs prints usage help if no params are given. + +Tip: If you are building Spark and examples repeatedly, export USE_FSC=1 +to have the Makefile use the fsc compiler daemon instead of scalac. |
