Review Comment:
no, I tried to use "spark.shuffle.compress". But rssConf removes "spark."
prefix. And in spark2 module, the referenced spark version is too old which
doesn't have below definition in spark's config object. So, I have to declare
it in RssClientConfig.
private[spark] val SHUFFLE_COMPRESS =
ConfigBuilder("spark.shuffle.compress")

"spark.io.compression.codec.")
