    Description

      for long running queries with multiple map-reduce jobs - this should help in dealing with any transient cluster failures without having to re-running all the tasks.

      ideally - the entire plan can be serialized out and the actual process of executing the workflow can be left to a pluggable workflow execution engine (since this is a problem that has been solved many times already).
