HiveColumnarLoader	Loader for Hive RC Columnar files. Supports the following types: * Hive Type Pig Type from DataType string CHARARRAY int INTEGER bigint or long LONG float float double DOUBLE boolean BOOLEAN byte BYTE array TUPLE map MAP Partitions The input paths are scanned by the loader for [partition name]=[value] patterns in the subdirectories.
