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.
is - how to co-group data from two
> dataframes based on a key? I think for RDD's cogroup in PairRDDFunctions is
> a way. I am not sure if something similar is available for DataFrames.
