---------------------------------------
Summary: Incorrect error message when grouping function used with
wrong types
Key: SPARK-19928
URL: https://issues.apache.org/jira/browse/SPARK-19928
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.2.0
Reporter: Jacek Laskowski
Priority: Minor
Despite `grouping` being used with no {{GroupingSets/Cube/Rollup}} the message
is plain wrong as the number of arguments for the function is indeed correct
(but failed type checking).

function grouping; line 1 pos 7
