@InterfaceAudience.Public @InterfaceStability.Stable 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 significant 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.
