Redesign Tool and ToolBase API and releted functionality
--------------------------------------------------------
Key: HADOOP-1436
URL: https://issues.apache.org/jira/browse/HADOOP-1436
Project: Hadoop
Issue Type: Improvement
Components: util
Affects Versions: 0.14.0
Reporter: Enis Soztutar
Fix For: 0.14.0
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)
