Subject [jira] Created: (HADOOP-6866) Tool interface should also support getUsage()
Date Mon, 19 Jul 2010 08:08:50 GMT
Tool interface should also support getUsage()

                 Key: HADOOP-6866
                 URL: https://issues.apache.org/jira/browse/HADOOP-6866
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Amar Kamat

Currently each and every _tool_ implementing the {{Tool}} interface is forced to manage their
usage string. Since its a common piece of code, its better we factor it out. This can be useful
in the following ways
# A proper lib like support for usage strings
# Forcing _tools_ (implementers of {{Tool}}) to expose their usage string
# Test cases can now use these well defined and exposed usage strings to test
