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

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

Modifier and Type	Class and Description
class	AllLoader The AllLoader provides the ability to point pig at a folder that contains files in multiple formats e.g.
class	CSVExcelStorage CSV loading and storing with support for multi-line fields, and escaping of delimiters and double quotes within fields; uses CSV conventions of Excel 2007.
class	FixedWidthLoader A fixed-width file loader.

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	HiveColumnarStorage
class	IndexedStorage IndexedStorage is a form of PigStorage that supports a per record seek.
