Interface | Description |
---|---|
ComposableInputFormat<K extends WritableComparable,V extends Writable> |
Refinement of InputFormat requiring implementors to provide
ComposableRecordReader instead of RecordReader.
|
ComposableRecordReader<K extends WritableComparable,V extends Writable> |
Additional operations required of a RecordReader to participate in a join.
|
ResetableIterator<T extends Writable> |
This defines an interface to a stateful Iterator that can replay elements
added to it directly.
|
Class | Description |
---|---|
ArrayListBackedIterator<X extends Writable> |
This class provides an implementation of ResetableIterator.
|
CompositeInputFormat<K extends WritableComparable> |
An InputFormat capable of performing joins over a set of data sources sorted
and partitioned the same way.
|
CompositeInputSplit |
This InputSplit contains a set of child InputSplits.
|
CompositeRecordReader<K extends WritableComparable,V extends Writable,X extends Writable> |
A RecordReader that can effect joins of RecordReaders sharing a common key
type and partitioning.
|
InnerJoinRecordReader<K extends WritableComparable> |
Full inner join.
|
JoinRecordReader<K extends WritableComparable> |
Base class for Composite joins returning Tuples of arbitrary Writables.
|
MultiFilterRecordReader<K extends WritableComparable,V extends Writable> |
Base class for Composite join returning values derived from multiple
sources, but generally not tuples.
|
OuterJoinRecordReader<K extends WritableComparable> |
Full outer join.
|
OverrideRecordReader<K extends WritableComparable,V extends Writable> |
Prefer the "rightmost" data source for this key.
|
Parser |
Very simple shift-reduce parser for join expressions.
|
Parser.Node | |
Parser.NodeToken | |
Parser.NumToken | |
Parser.StrToken | |
Parser.Token |
Tagged-union type for tokens from the join expression.
|
StreamBackedIterator<X extends Writable> |
This class provides an implementation of ResetableIterator.
|
TupleWritable |
Writable type storing multiple
Writable s. |
WrappedRecordReader<K extends WritableComparable,U extends Writable> |
Proxy class for a RecordReader participating in the join framework.
|
Enum | Description |
---|---|
Parser.TType |
