Not a hack, this is documented here: http://spark.apache.org/docs/0.9.1/configuration.html, and is in fact the proper way of setting per-application Spark configurations.
Additionally, you can specify default Spark configurations so you don't need to manually set it for all applications. If you are running Spark 0.9 or before, then you could set them through the environment variable SPARK_JAVA_OPTS in conf/spark-env.sh. As of Spark 1.0, however, this mechanism is deprecated. The new way of setting default Spark configurations is through conf/spark-defaults.conf in the following format spark.config.one value spark.config.two value2 More details are documented here: http://people.apache.org/~pwendell/spark-1.0.0-rc7-docs/configuration.html. 2014-05-16 15:16 GMT-07:00 Theodore Wong <t...@tmwong.org>: > I found that the easiest way was to pass variables in the Spark > configuration > object.
