The normalization is not done by StructObjectInspector or
OrcStructObjectInspector, but in `SemanticAnalyzer` of Hive. I've checked with
Hive, even the orc column names are in capital, Hive works well, the only thing
I am not sure is about the column pruning and predicate push down, seems
"explain extended select xx" of Hive doesn't give those information, maybe
@zhzhan can give some comments on this.
