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.
