Uses of LoadMetadata in org.apache.pig.piggybank.storage

Classes in org.apache.pig.piggybank.storage that implement LoadMetadata

class	AllLoader The AllLoader provides the ability to point pig at a folder that contains files in multiple formats e.g.
class	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. If detected these partitions are appended to the table schema. For example if you have the directory structure:
class	JsonMetadata Reads and Writes metadata using JSON in metafiles next to the data.
class	PigStorageSchema This Load/Store Func reads/writes metafiles that allow the schema and aliases to be determined at load time, saving one from having to manually enter schemas for pig-generated datasets.
