HiveColumnarLoader
Loader for Hive RC Columnar files. Supports the following types: * Hive TypePig Type from DataType stringCHARARRAY intINTEGER bigint or longLONG floatfloat doubleDOUBLE booleanBOOLEAN byteBYTE arrayTUPLE mapMAP Usage 1: To load a hive table: uid bigint, ts long, arr ARRAY
a = LOAD 'file' USING HiveColumnarLoader("uid bigint, ts long, arr array
Usage 2:To load a hive table: uid bigint, ts long, arr ARRAY date partitioned hive table.
a = LOAD 'file' USING HiveColumnarLoader("uid bigint, ts long, arr array
Usage 3:To load a hive table: uid bigint, ts long, arr ARRAY a = LOAD 'file' USING HiveColumnarLoader("uid bigint, ts long, arr array To load a hive table: uid bigint, ts long, arr ARRAY a = LOAD 'file' USING HiveColumnarLoader("uid bigint, ts long, arr array The schema definition must be column name followed by a space then a comma then no space and the next column name and so on. This so column1 string, column2 string will not word, it must be column1 string,column2 string Date partitioning Hive date partition folders must have format daydate=[date]. |
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. |
