> Currently ORCFile does not support predicate pushdown for complex datatypes like map, array and struct while Parquet does. Came across this during discussion of PIG-3760. Our users have a lot of map and struct (tuple in pig) columns and most of the filter conditions are on them. Would be great to have support added for them in ORC
