Description

This JIRA describes a small improvement in an error message as below:

scala> spark.range(1).select($"col".cast("aa"))
org.apache.spark.sql.catalyst.parser.ParseException:
DataType aa() is not supported.(line 1, pos 0)

== SQL ==
aa
^^^

Currently, when the types are invalid, it looks printing empty parentheses.
