Hi guys,
As we know, hqlContext support rollup like this:
hiveContext.sql("select a, b, sum(c) from t group by a, b with rollup")
And I also knows that dataframe provides rollup function to support it:
dataframe.rollup($"a", $"b").agg(Map("c" -> "sum"))
But in my scenario, I'd better use sql syntax in SqlContext to support rollup
it seems like what HqlContext does. Any suggestion?
Thanks.
Regards,Yi Zhang
