      Description

      Currently Impala does not support ORDER BY for GROUP_CONCAT(), nor DISTINCT, but seems ordered lists would be most useful of those two if forced to choose just one.

      MySQL syntax:

      GROUP_CONCAT([DISTINCT] expr [,expr ...]
                   [ORDER BY {unsigned_integer | col_name | expr}
                       [ASC | DESC] [,col_name ...]]
                   [SEPARATOR str_val])
