Thomas Graves commented on SPARK-1680:
--------------------------------------
so what do we want to do here. Do we want to expose spark.executorEnv. to the
user to allow them to set environment variables? I assume since it isn't
documented it wasn't meant for end users but perhaps we just missed documenting
it. I would like to add a config to replace the env variable
SPARK_YARN_USER_ENV.
Either way I will probably need another config to set env variables on the
application master. I could make that one yarn specific like
spark.yarn.appMasterEnv.

> We should make this consistent between YARN and Standalone. Basically, YARN
