[GitHub] [pinot] ksnijjer opened a new issue #8290: Improve error message when aggregate function is applied to a nun-numeric column

[GitBox]

ksnijjer opened a new issue #8290:
URL: https://github.com/apache/pinot/issues/8290


   Pinot currently supports aggregation functions for e.g max() on numeric 
values only, however if you run a query where a non-numeric column is passed as 
a value then error message generated is really vague and totally misleading:

   We should have a explicit error message indicating lack of support for 
non-numeric data and the offending function used in the query.
