Removed Classes and Interfaces | |
|
This interface is used to implement classes that can perform both Load and Store functionalities in a symmetric fashion (thus reversible). |
|
A grouping of data on that can be processed individually by Pig. |
|
Produces independent slices of data from a given location to be processed in parallel by Pig. |
|
A Class which will encapsulate metadata information that a OutputFormat (or possibly StoreFunc) may want to know about the data that needs to be stored. |
Added Classes and Interfaces | |
|
|
|
This interface implemented by 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. |
|
A class to communicate Filter expressions to LoadFuncs |
|
|
|
|
|
|
|
|
|
This class provides an implementation of OrderedLoadFunc interface which can be optionally re-used by LoadFuncs that use FileInputFormat by having this as a super class |
|
This class can be used to represent a relative position in a file. |
|
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. |
|
|
|
This interface defines how to retrieve metadata related to data to be loaded. |
|
This interface defines how to communicate to Pig what functionality can be pushed into the loader. |
|
Set of possible operations that Pig can push down to a loader. |
|
|
|
|
|
|
|
Implementing this interface indicates to Pig that a given loader can be used for MergeJoin. |
|
The following enum will contain the general counters that pig uses. |
|
|
|
The interface used for the custom mapping of a Tuple to a byte array. |
|
|
|
|
|
|
|
|
|
|
|
A class representing information about a sort column in SortInfo |
|
|
|
Class to communicate sort column information based on order by statment's sort columns and schema |
|
This interface is used to implement functions to write records from a dataset. |
|
This interface defines how to write metadata related to data to be loaded. |
|
The interface used for the custom mapping of a byte array received from the stdout of the streaming process to a Tuple This interface together with PigToStream is designed to provide a common protocol for data exchange between Pig runtime and streaming executables. |
Changed Classes | |
|
Class to represent a UDF specification - essentially encapsulates the class name and the arguments to the constructor |
|
LoadFunc provides functions directly associated with reading records from data set. |
|
This class is the program's connection to Pig. |
|
An enum to enumerate the warning types in Pig |
|
This abstract class is used to implement functions to write records from a dataset. |
