Added Classes and Interfaces
CombineFileInputFormat An abstract InputFormat that returns i InputFormat#getSplits(JobContext) method.
CombineFileRecordReader A generic RecordReader that can hand out different recordReaders for each chunk in a CombineFileSplit A CombineFileSplit can combine data chunks from multiple files.
CombineFileSplit A sub-collection of input files.
DelegatingInputFormat An InputFormat that delegates behavior of paths to multiple other InputFormats.
DelegatingMapper An Mapper that delegates behavior of paths to multiple other mappers.
DelegatingRecordReader This is a delegating RecordReader which delegates the functionality to the underlying record reader in TaggedInputSplit
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.
MultipleInputs This class supports MapReduce jobs that have multiple input paths with a different InputFormat and Mapper for each path
NLineInputFormat NLineInputFormat which splits N lines of input as one split.
SequenceFileAsBinaryInputFormat InputFormat reading keys values from SequenceFiles in binary (raw) format.
SequenceFileAsBinaryInputFormat.
SequenceFileAsBinaryRecordReader
Read records from a SequenceFile as binary (raw) bytes.
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.
SequenceFileAsTextRecordReader This class converts the input keys and values to their String forms by calling toString() method.
SequenceFileInputFilter A class that allows a map/red job to work on a sample of sequence files.
SequenceFileInputFilter.
Filter
filter interface
SequenceFileInputFilter.
FilterBase
base class for Filters
SequenceFileInputFilter.
MD5Filter
This class returns a set of records by examing the MD5 digest of its key against a filtering frequency f.
SequenceFileInputFilter.
PercentFilter
This class returns a percentage of records The percentage is determined by a filtering frequency f using the criteria record# % f == 0.
SequenceFileInputFilter.
RegexFilter
Records filter by matching key to regex
