Changed Classes and Interfaces
ArrayListBackedIterator	This class provides an implementation of ResetableIterator.
ComposableInputFormat	Refinement of InputFormat requiring implementors to provide ComposableRecordReader instead of RecordReader.
ComposableRecordReader	Additional operations required of a RecordReader to participate in a join.
CompositeInputFormat	An InputFormat capable of performing joins over a set of data sources sorted and partitioned the same way.
CompositeRecordReader	A RecordReader that can effect joins of RecordReaders sharing a common key type and partitioning.
InnerJoinRecordReader	Full inner join.
JoinRecordReader	Base class for Composite joins returning Tuples of arbitrary Writables.
JoinRecordReader.JoinDelegationIterator	Since the JoinCollector is effecting our operation we need only provide an iterator proxy wrapping its operation.
MultiFilterRecordReader	Base class for Composite join returning values derived from multiple sources but generally not tuples.
MultiFilterRecordReader. MultiFilterDelegationIterator	Proxy the JoinCollector but include callback to emit.
OuterJoinRecordReader	Full outer join.
OverrideRecordReader	Prefer the "rightmost" data source for this key.
Parser.Node
Parser.TType
ResetableIterator	This defines an interface to a stateful Iterator that can replay elements added to it directly.
ResetableIterator.EMPTY
StreamBackedIterator	This class provides an implementation of ResetableIterator.
TupleWritable	Writable type storing multiple Thi is *not* a general-purpose tuple type.
WrappedRecordReader	Proxy class for a RecordReader participating in the join framework.
