Michael Gummelt 235cb256d0 [SPARK-16194] Mesos Driver env vars ... ## What changes were proposed in this pull request? Added new configuration namespace: spark.mesos.env.* This allows a user submitting a job in cluster mode to set arbitrary environment variables on the driver. spark.mesos.driverEnv.KEY=VAL will result in the env var "KEY" being set to "VAL" I've also refactored the tests a bit so we can re-use code in MesosClusterScheduler. And I've refactored the command building logic in `buildDriverCommand`. Command builder values were very intertwined before, and now it's easier to determine exactly how each variable is set. ## How was this patch tested? unit tests Author: Michael Gummelt <mgummelt@mesosphere.io> Closes #14167 from mgummelt/driver-env-vars.		2016-07-21 18:29:00 +01:00
