>          Issue Type: Bug
>          Components: File Formats
>    Affects Versions: 1.2.0

> {code}
>     String filterText = filterExpr.getExprString();
>     String filterExprSerialized = Utilities.serializeExpression(filterExpr);
> {code}
> the serializeExpression initializes Kryo and produces a new packed object for every split.
> HiveInputFormat::getRecordReader -> pushProjectionAndFilters -> pushFilters.
> And Kryo is very slow to do this for a large filter clause.
