[jira] [Created] (SPARK-16744) spark.yarn.appMasterEnv handling assumes values should be appended

Kevin Grealish created SPARK-16744:
--------------------------------------

             Summary: spark.yarn.appMasterEnv handling assumes values should be appended
                 Key: SPARK-16744
                 URL: https://issues.apache.org/jira/browse/SPARK-16744
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 2.0.0, 1.6.2, 1.6.1, 1.6.0
         Environment: YARN
            Reporter: Kevin Grealish


When processing environment variables set via the conf setting spark.yarn.appMasterEnv.*, if there is an existing value the new value is appended assuming it is a CLASSPATH like value. This does not work for most environment variables, for example PYSPARK_PYTHON.
