from two
dataframes based on a key? I think for RDD's cogroup in PairRDDFunctions is

I have two dataframes like this
student_rdf = (studentid, name, ...)
student_result_rdf = (studentid, gpa, ...)
we need to join this two dataframes. we are now doing like this,
student_rdf.join(student_result_rdf, student_result_rdf[studentid]
== student_rdf[studentid])
So it is simple.
