   @dh20 
   I run the following query using apache master
   ```
   SELECT concat_ws(',', array(1, 2, 3));
   ```
   and got
   ```
   Argument 2 of function CONCAT_WS must be "string or array<string>", but "array<int>" was found.
   ```
   This seems to be ok since it clearly indicates that an `array of int` was passed but an `array of string` is expected.
