      Description

      Proposing a patch that introduces a new annotation @Checkpointable that represents to the framework property of user-supplied classes (e.g., Reducer, OutputCommiter). The intended semantics is that a tagged class is safe to be preempted between invocations.

      (this is in spirit similar to the Output Contracts of Nephele/PACT )
