>             Project: Hive
>          Issue Type: Bug
>          Components: Query Planning
>    Affects Versions: 1.3.0, 2.0.0
>            Reporter: Gopal V
>            Assignee: Navis

>       String funcText,
>       List<ExprNodeDesc> children) throws UDFArgumentException {
> ...
>  if (genericUDF instanceof GenericUDFBaseCompare && children.size() == 2) {
>       TypeInfo oiTypeInfo0 = children.get(0).getTypeInfo();
>       TypeInfo oiTypeInfo1 = children.get(1).getTypeInfo();
>       SessionState ss = SessionState.get();
>       Configuration conf = (ss != null) ? ss.getConf() : new Configuration();
> {code}
> This is both a SessionState.get() which is a threadlocal lookup or worse, a  new Configuration()  which means XML parsing of multiple files for each equality expression in the query.
