Subject: Hive UDFs
I know the typical way to apply a hive UDF to a dataframe is basically
something like:
dataframe.selectExpr("reverse(testString) as reversedString")
Is there a way to apply the hive UDF just to a single row and get a row back?
Something like:
dataframe.first.selectExpr("reverse(testString) as reversedString")
Thanks in advance!
