To summarize, es-hadoop is aware that from command line, non spark.*
parameters get ignored so they created a workaround to allow setting the
parameters through spark.es.* parameters.
Either way, as I suspected, the parameters themselves are serialized
separately to the executors and not through the spark configuration.
I must say that I still think that blocking any non-spark configuration
settings is overprotective relative to what you can perform in code, but I am
no longer blocked by this issue.
