> ORC evaluates predicate expressions to select row groups that satisfy predicate condition. There can be exceptions (mostly ClassCastException) when data types of predicate constant and min/max values are different. 
> To avoid this patch catches any such exception and provides a default behaviour i.e; selecting the row group.
