---|---|
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. |

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 |

JobClient
JobClient is the primary interface for the user-job to interact
with the JobTracker . |

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 . |
