public interface Progressable

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 an insignificant amount of time since, in-lieu of the reported progress, the framework has to assume that an error has occured and time-out the operation.
