question: public static SparkConf createSystemMLSparkConf ( ) { SparkConf conf = new SparkConf ( ) ; conf . set ( "spark.driver.maxResultSize" , "0" ) ; if ( FAIR_SCHEDULER_MODE ) { conf . set ( "spark.scheduler.mode" , "FAIR" ) ; } if ( ! conf . contains ( "spark.locality.wait" ) ) { conf . set ( "spark.locality.wait" , "5s" ) ; } return conf ; }
target:  Sets up a SystemML-preferred Spark configuration based on the implicit default configuration (as passed via configurations from outside).
