spark tests fail with out of memory while building the package

[srikanthadibhatla]

i have tried to set the spark.driver.memory=4g property @ "Hydrograph\hydrograph.engine\hydrograph.engine.spark\src\main\resources\runtime_service" but it doesnt seem to work.

ERROR spark.SparkContext: Error initializing SparkContext.
java.lang.IllegalArgumentException: System memory 259522560 must be at least 471859200. Please increase heap size using the --driver-memory option or spark.driver.memory in Spark configuration.
