Class Summary
CombineFileInputFormat<K,V> | An abstract `InputFormat` that returns `CombineFileSplit`'s in `InputFormat.getSplits(JobContext)` method.
CombineFileRecordReader<K,V> | A generic RecordReader that can hand out different recordReaders for each chunk in a `CombineFileSplit`.
CombineFileSplit | A sub-collection of input files.
DelegatingInputFormat<K,V> | An `InputFormat` that delegates behavior of paths to multiple other InputFormats.
DelegatingMapper<K1,V1,K2,V2> | An `Mapper` that delegates behavior of paths to multiple other mappers.
DelegatingRecordReader<K,V> | This is a delegating RecordReader, which delegates the functionality to the underlying record reader in `TaggedInputSplit`
FileInputFormat<K,V> | A base class for file-based `InputFormat`s.
FileSplit | A section of an input file.
KeyValueLineRecordReader | This class treats a line in the input as a key/value pair separated by a separator character.
KeyValueTextInputFormat | An `InputFormat` for plain text files.
LineRecordReader | Treats keys as offset in file and value as line.
MultipleInputs | This class supports MapReduce jobs that have multiple input paths with a different `InputFormat` and `Mapper` for each path
SequenceFileInputFormat<K,V> | An `InputFormat` for `SequenceFile`s.
SequenceFileRecordReader<K,V> | An `RecordReader` for `SequenceFile`s.
TextInputFormat | An `InputFormat` for plain text files.

Exception Summary
