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. |
