## Uses of Interface
org.apache.hadoop.mapred.OutputFormat

Packages that use OutputFormat
org.apache.hadoop.contrib.index.mapred |
org.apache.hadoop.examples.terasort | This package consists of 3 map/reduce applications for Hadoop to compete in the annual terabyte sort competition.
org.apache.hadoop.mapred | A software framework for easily writing applications which process vast amounts of data (multi-terabyte data-sets) parallelly on large clusters (thousands of nodes) built of commodity hardware in a reliable, fault-tolerant manner.
org.apache.hadoop.mapred.lib | Library of generally useful mappers, reducers, and partitioners.
org.apache.hadoop.mapred.lib.db | org.apache.hadoop.mapred.lib.db Package

Uses of OutputFormat in org.apache.hadoop.contrib.index.mapred

Classes in org.apache.hadoop.contrib.index.mapred that implement OutputFormat
`class` | `IndexUpdateOutputFormat` The record writer of this output format simply puts a message in an output path when a shard update is done.

Uses of OutputFormat in org.apache.hadoop.examples.terasort

Classes in org.apache.hadoop.examples.terasort that implement OutputFormat
`class` | `TeraOutputFormat` A streamlined text output format that writes key, value, and "\r\n".

Uses of OutputFormat in org.apache.hadoop.mapred

Classes in org.apache.hadoop.mapred that implement OutputFormat
`class` | `FileOutputFormat<K,V>` A base class for `OutputFormat`.
`class` | `MapFileOutputFormat` An `OutputFormat` that writes `MapFile`s.
`class` | `SequenceFileAsBinaryOutputFormat` An `OutputFormat` that writes keys, values to `SequenceFile`s in binary(raw) format
`class` | `SequenceFileOutputFormat<K,V>` An `OutputFormat` that writes `SequenceFile`s.
`class` | `TextOutputFormat<K,V>` An `OutputFormat` that writes plain text files.

Methods in org.apache.hadoop.mapred that return OutputFormat
`OutputFormat` | `JobConf.getOutputFormat()` Get the `OutputFormat` implementation for the map-reduce job, defaults to `TextOutputFormat` if not specified explicity.

Method parameters in org.apache.hadoop.mapred with type arguments of type OutputFormat
`void` | `JobConf.setOutputFormat(Class<? extends OutputFormat> theClass)` Set the `OutputFormat` implementation for the map-reduce job.

Uses of OutputFormat in org.apache.hadoop.mapred.lib

Classes in org.apache.hadoop.mapred.lib that implement OutputFormat
`class` | `MultipleOutputFormat<K,V>` Deprecated. Use `MultipleOutputs` instead
`class` | `MultipleSequenceFileOutputFormat<K,V>` Deprecated. Use `MultipleOutputs` instead
`class` | `MultipleTextOutputFormat<K,V>` Deprecated. Use `MultipleOutputs` instead
`class` | `NullOutputFormat<K,V>` Consume all outputs and put them in /dev/null.

Methods in org.apache.hadoop.mapred.lib that return types with arguments of type OutputFormat
`static Class<? extends OutputFormat>` | `MultipleOutputs.getNamedOutputFormatClass(JobConf conf, String namedOutput)` Deprecated. Returns the named output OutputFormat.

Method parameters in org.apache.hadoop.mapred.lib with type arguments of type OutputFormat
`static void` | `MultipleOutputs.addMultiNamedOutput(JobConf conf, String namedOutput, Class<? extends OutputFormat> outputFormatClass, Class<?> keyClass, Class<?> valueClass)` Deprecated. Adds a multi named output for the job.
`static void` | `MultipleOutputs.addNamedOutput(JobConf conf, String namedOutput, Class<? extends OutputFormat> outputFormatClass, Class<?> keyClass, Class<?> valueClass)` Deprecated. Adds a named output for the job.

Uses of OutputFormat in org.apache.hadoop.mapred.lib.db

Classes in org.apache.hadoop.mapred.lib.db that implement OutputFormat
`class` | `DBOutputFormat<K extends DBWritable,V>` Deprecated. Use org.apache.hadoop.mapreduce.lib.db.DBOutputFormat instead
