Interface Summary
SequenceFileInputFilter.Filter | filter interface

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
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<K,V> | A class that allows a map/red job to work on a sample of sequence files.
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
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
InvalidInputException | This class wraps a list of problems with the input, so that the user can get a list of problems together instead of finding and fixing them one by one.
