Description
| Interface Summary | |
|---|---|
| SerializableSupplier<T> | An extension of Guava's Supplier interface that indicates that an instance
will also implement Serializable, which makes this object suitable for use
with Crunch's DoFns when we need to construct an instance of a non-serializable
type for use in processing. |
| Class Summary | |
|---|---|
| CrunchTool | An extension of the Tool interface that creates a Pipeline
instance and provides methods for working with the Pipeline from inside of
the Tool's run method. |
| DelegatingReadableData<S,T> | Implements the ReadableData<T> interface by delegating to an ReadableData<S> instance
and passing its contents through a DoFn<S, T>. |
| DistCache | Provides functions for working with Hadoop's distributed cache. |
| DoFnIterator<S,T> | An Iterator<T> that combines a delegate Iterator<S> and a DoFn<S, T>, generating
data by passing the contents of the iterator through the function. |
| PartitionUtils | Helper functions and settings for determining the number of reducers to use in a pipeline job created by the Crunch planner. |
| Tuples | Utilities for working with subclasses of the Tuple interface. |
| Tuples.PairIterable<S,T> | |
| Tuples.QuadIterable<A,B,C,D> | |
