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` `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.
