> 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.
