```
Cause:
sqlParser.parseExpression(where) gives unresolved expression. Most of the
filters doesn't need it to be resolved. Some special filter like In-filter
needs resolved type because based on datatype it creates HashSet.
Solution:
Use a resolved expression.
I found a hacky sparkish way to achieve it. Will raise a PR for the same.
