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 InputFormats.
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 SequenceFiles.
SequenceFileRecordReader<K,V> An RecordReader for SequenceFiles.
TextInputFormat An InputFormat for plain text files.
