## Uses of Interface
org.apache.hadoop.util.Tool

Packages that use Tool
org.apache.hadoop.examples | Hadoop example code.
org.apache.hadoop.examples.dancing | This package is a distributed implementation of Knuth's dancing links algorithm that can run under Hadoop.
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.fs | An abstract file system API.
org.apache.hadoop.fs.s3 | A distributed, block-based implementation of `FileSystem` that uses Amazon S3 as a backing store.
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.pipes | Hadoop Pipes allows C++ code to use Hadoop DFS and map/reduce.
org.apache.hadoop.mapred.tools |
org.apache.hadoop.streaming | `Hadoop Streaming` is a utility which allows users to create and run Map-Reduce jobs with any executables (e.g.
org.apache.hadoop.tools |
org.apache.hadoop.util | Common utilities.

Uses of Tool in org.apache.hadoop.examples

Classes in org.apache.hadoop.examples that implement Tool
`class` | `DBCountPageView` This is a demonstrative program, which uses DBInputFormat for reading the input data from a database, and DBOutputFormat for writing the data to the database.
`class` | `Grep`
`class` | `Join` This is the trivial map/reduce program that does absolutely nothing other than use the framework to fragment and sort the input values.
`class` | `MultiFileWordCount` MultiFileWordCount is an example to demonstrate the usage of MultiFileInputFormat.
`class` | `PiEstimator` A Map-reduce program to estimate the value of Pi using quasi-Monte Carlo method.
`class` | `RandomTextWriter` This program uses map/reduce to just run a distributed job where there is no interaction between the tasks and each task writes a large unsorted random sequence of words.
`class` | `RandomWriter` This program uses map/reduce to just run a distributed job where there is no interaction between the tasks and each task write a large unsorted random binary sequence file of BytesWritable.
`class` | `SleepJob` Dummy class for testing MR framefork.
`class` | `Sort<K,V>` This is the trivial map/reduce program that does absolutely nothing other than use the framework to fragment and sort the input values.
