Package org.apache.tez.runtime.api

Interface Summary

Input	Represents an input through which a TezProcessor receives data on an edge.
InputReadyCallback	Used temporarily until MergedInputs have access to a context.
LogicalInput	An @link Input which handles all incoming physical connections on an edge.
LogicalIOProcessor	Represents a processor which consumes LogicalInputs and produces LogicalOutputs
LogicalOutput	An @link Output which handles all outgoing physical connections on an edge.
MemoryUpdateCallback	This interface will be used by Tez to inform components about available memory.
Output	Represents an Output through which a TezProcessor writes information on an edge.
OutputCommitterContext	Context through which the OutputCommitter can access all the relevant information that it needs.
Processor	Processor represents the Tez entity responsible for consuming Input and producing Output.
Reader	A Reader represents the data being read in an Input
TezInputContext	Context handle for the Input to initialize itself.
TezOutputContext	Context handle for the Output to initialize itself.
TezProcessorContext	Context handle for the Processor to initialize itself.
TezRootInputInitializer	TezRootInputInitializers are used to initialize root vertices within the AM.
TezRootInputInitializerContext
TezTaskContext	Base interface for Context classes used to initialize the Input, Output and Processor instances.
Writer	A Writer represents the data being written by an Output

Class Summary

Event	Base class for all events generated within the Tez execution engine.
MergedLogicalInput	A LogicalInput that is used to merge the data from multiple inputs and provide a single Reader to read that data.
OutputCommitter	OutputCommitter to "finalize" the output and make it user-visible if needed.
