A facility for reporting progress.
Clients and/or applications can use the provided Progressable to explicitly report progress to the Hadoop framework. This is especially important for operations which take significant amount of time since, in-lieu of the reported progress, the framework has to assume that an error has occurred and time-out the operation.
