@jackylk Agreed with @xuchuanyin, Sparkâs storage levels are meant to
provide different trade-offs between memory usage and CPU efficiency. So
different environment correspond to different storage level. So here we'd
better make a conf named 'storage_level', and the default value of it is
MEMORY_ONLY(the same to default value in spark). We can get more info about
storage level in spark
website.(http://spark.apache.org/docs/latest/rdd-programming-guide.html#rdd-persistence)
