Package org.apache.pig

Added Interfaces
NonFSLoadFunc	Marker interface to distinguish LoadFunc implementations that don't use file system sources.

 

Changed Classes and Interfaces
Accumulator	An interface that allows UDFs that take a bag to accumulate tuples in chunks rather than take the whole set at once.
Algebraic	An interface to declare that an EvalFunc's calculation can be decomposed into intitial intermediate and final steps.
CollectableLoadFunc	This interface implemented by a LoadFunc implementations indicates to Pig that it has the capability to load data such that all instances of a key will occur in same split.
ErrorHandler	The interface that handles errors thrown by the StoreFuncInterface#putNext(Tuple)
ErrorHandling	A StoreFunc should implement this interface to enable handling errors during {@code StoreFunc#putNext(Tuple)}
EvalFunc	The class is used to implement functions to be applied to fields in a dataset.
ExceptionalFunction	An interface that captures a unit of work against an item where an exception might be thrown.
ExecType	The type of query execution.
Function	A convenience typedef that ties into both google's {@code Function} and {@code ExceptionalFunction}.
IndexableLoadFunc	This class is intended for use by LoadFunc implementations which have an internal index for sorted data and can use the index to support merge join in Pig.
LoadCaster	An interface that provides cast implementations for load functions.
LoadMetadata	This interface defines how to retrieve metadata related to data to be loaded.
LoadPredicatePushdown	This interface defines how a loader can support predicate pushdown.
LoadPushDown	This interface defines how to communicate to Pig what functionality can be pushed into the loader.
OrderedLoadFunc	Implementing this interface indicates to Pig that a given loader can be used for MergeJoin.
OverwritableStoreFunc	A StoreFunc should implement this interface to enable overwriting its store/output location if it already exists.
PigConfiguration	Container for static configuration strings defaults etc.
PigServer	A class for Java programs to connect to Pig.
PigToStream	@deprecated Use org.apache.pig.PigStreamingBase
PigWarning	An enum to enumerate the warning types in Pig
StoreCaster	An interface that provides methods for converting Pig internal types to byte[].
StoreFuncInterface	StoreFuncs take records from Pig's processing and store them into a data store.
StoreMetadata	This interface defines how to write metadata related to data to be stored.
StoreResources	This interface allow StoreFunc to specify resources needed in distributed cache.
StreamToPig	@deprecated Use org.apache.pig.PigStreamingBase
TerminatingAccumulator	This is an interface which if implemented allows an Accumulator function to signal that it can terminate early.
