Documentation for Tool interface is a bit busted
------------------------------------------------
Key: HADOOP-4611
URL: https://issues.apache.org/jira/browse/HADOOP-4611
Project: Hadoop Core
Issue Type: Bug
Components: documentation, util
Reporter: Jeff Hammerbacher
Priority: Minor
The documentation for the Tool interface will not work out of the box. It seems
to have taken the Sort() implementation in examples, but has ripped out some
important information.
1) args[1] and args[2] should probably be args[0] and args[1], as most
MapReduce tasks don't take the first argument that examples.jar takes
2) int run() needs to actually return an int
3) JobConf.setInputPath() and JobConf.setOutputPath() are deprecated.
4) the call to ToolRunner.run() in main() should take "new MyApp()" instead of
"Sort()" as an argument
More generally, a working implementation of Tool in the docs would be handy.
