Enis Soztutar updated HADOOP-1436:
----------------------------------
Attachment: redesignToolAndRelated_v1.0.patch
redesignToolAndRelated_v1.0.patch
This patch is intended for review. implemented basic changes discussed in
HADOOP-1425. this patch :
1. deprecates ToolBase
2. introduces HadoopCommandLineParser class to parse command line options
3. ToolRunner class to run classes implementing Tool
Below are the points that i would be glad to be reviewed :
1. naming HadoopCommandLineParser (should it be CommandLineParser, or
ArgumentParser, etc)
2. adding {{Tool.getOptions()}} and changing {{Tool#run(CommandLine)}}. All the
actual use cases for ToolBase do not use Commons CLI.
3. -conf argument in

> With the discussion from HADOOP-1425, we need better abstraction and better
> tool runner utilities.
> 1. Classes do not need to extend ToolBase
> 2. functions for parsing general HadoopCommands (-fs, -conf, -jt) should be
> public
> 3. We need a ToolRunner, or similar functionality
> 4. Also we need each class (implementing Tool) to be runnable (main method)
> 5. CLI objects can be passed to run method of the Tool class (arguable)
