I agree SPARK_AUTH_SECRET_CONF is awkward and not really secure, when I
initially did this , this is what was requested by other committers since
standalone and mesos needed more security work around it anyway.
I don't follow how the MesosSecretConfig is going to be used fully. Are
these just regular spark configs passed around or distributed through mesos
somehow?
