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

Packages that use Tool
org.apache.hadoop.dfs A distributed implementation of FileSystem
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.fs An abstract file system API. 
org.apache.hadoop.fs.s3 A distributed implementation of FileSystem that uses Amazon S3
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.util Common utilities. 
 

Uses of Tool in org.apache.hadoop.dfs
 

Classes in org.apache.hadoop.dfs that implement Tool
 class DFSAdmin
          This class provides some DFS administrative access.
 class DFSck
          This class provides rudimentary checking of DFS volumes for errors and sub-optimal conditions.
 

Uses of Tool in org.apache.hadoop.examples
 

Classes in org.apache.hadoop.examples that implement Tool
 class Grep
           
 class PiEstimator
          A Map-reduce program to estimaate the valu eof Pi using 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
          This is the trivial map/reduce program that does absolutely nothing other than use the framework to fragment and sort the input values.
 class WordCount
          This is an example Hadoop Map/Reduce application.
 

Uses of Tool in org.apache.hadoop.examples.dancing
 

Classes in org.apache.hadoop.examples.dancing that implement Tool
 class DistributedPentomino
          Launch a distributed pentomino solver.
 

Uses of Tool in org.apache.hadoop.fs
 

Classes in org.apache.hadoop.fs that implement Tool
 class FsShell
          Provide command line access to a FileSystem.
 

Uses of Tool in org.apache.hadoop.fs.s3
 

Classes in org.apache.hadoop.fs.s3 that implement Tool
 class MigrationTool
           This class is a tool for migrating data from an older to a newer version of an S3 filesystem.
 

Uses of Tool in org.apache.hadoop.mapred
 

Classes in org.apache.hadoop.mapred that implement Tool
 class JobClient
          JobClient is the primary interface for the user-job to interact with the JobTracker.
 

Uses of Tool in org.apache.hadoop.util
 

Classes in org.apache.hadoop.util that implement Tool
 class CopyFiles
          A Map-reduce program to recursively copy directories between different file-systems.
 class ToolBase
          Deprecated. This class is depracated. Classes extending ToolBase should rather implement Tool interface, and use ToolRunner for execution functionality. Alternatively, GenericOptionsParser can be used to parse generic arguments related to hadoop framework.
 

Methods in org.apache.hadoop.util with parameters of type Tool
static int ToolRunner.run(Configuration conf, Tool tool, String[] args)
          Runs the given Tool by run(String[]), after parsing with the given generic arguments.
static int ToolRunner.run(Tool tool, String[] args)
          Runs the Tool with its Configuration.
