Vladimir Feinberg created SPARK-15972:
-----------------------------------------
Summary: GroupedData varargs arguments misnamed
Key: SPARK-15972
URL: https://issues.apache.org/jira/browse/SPARK-15972
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 2.0.0, 2.1.0
Reporter: Vladimir Feinberg
Priority: Trivial
Simple aggregation functions which take column names [[cols]] as varargs
arguments show up in documentation with the argument [[args]], but their
documentation refers to [[cols]].
The discrepancy is caused by an annotation, [[df_varargs_api]], which produces
a temporary function with arguments [[args]] instead of [[cols]], creating the
confusing documentation.
