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