bin/spark-submit will set some env variable, like SPARK_HOME, that Spark later
will use to locate the spark-defaults.conf from which default settings for
Spark will be loaded.
I would guess that some configuration option like spark.eventLog.enabled in the
spark-defaults.conf is skipped by directly using the SparkSubmit class instead
of “bin/spark-submit”.
The formal way to launch a Spark application within Java is to use
SparkLauncher. Remember to call SparkLaunch.setSparkHome() to set the Spark
Home directory.
