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.
