Classes in org.apache.hadoop.mapreduce.lib.fieldsel with annotations of type InterfaceStability.Stable
`class` | `FieldSelectionHelper` This class implements a mapper/reducer class that can be used to perform field selections in a manner similar to unix cut.
`class` | `FieldSelectionMapper<K,V>` This class implements a mapper class that can be used to perform field selections in a manner similar to unix cut.
`class` | `FieldSelectionReducer<K,V>` This class implements a reducer class that can be used to perform field selections in a manner similar to unix cut.

Uses of InterfaceStability.Stable in org.apache.hadoop.mapreduce.lib.input

Classes in org.apache.hadoop.mapreduce.lib.input with annotations of type InterfaceStability.Stable
`class` | `CombineFileInputFormat<K,V>` An abstract `InputFormat` that returns `CombineFileSplit`'s in `InputFormat.getSplits(JobContext)` method.
`class` | `CombineFileRecordReader<K,V>` A generic RecordReader that can hand out different recordReaders for each chunk in a `CombineFileSplit`.
`class` | `CombineFileSplit` A sub-collection of input files.
`class` | `KeyValueLineRecordReader` This class treats a line in the input as a key/value pair separated by a separator character.
`class` | `KeyValueTextInputFormat` An `InputFormat` for plain text files.
`class` | `MultipleInputs` This class supports MapReduce jobs that have multiple input paths with a different `InputFormat` and `Mapper` for each path
`class` | `NLineInputFormat` NLineInputFormat which splits N lines of input as one split.
`class` | `SequenceFileAsBinaryInputFormat` InputFormat reading keys, values from SequenceFiles in binary (raw) format.
`class` | `SequenceFileAsTextInputFormat` This class is similar to SequenceFileInputFormat, except it generates SequenceFileAsTextRecordReader which converts the input keys and values to their String forms by calling toString() method.
`class` | `SequenceFileAsTextRecordReader` This class converts the input keys and values to their String forms by calling toString() method.
`class` | `SequenceFileInputFilter<K,V>` A class that allows a map/red job to work on a sample of sequence files.
