----------------------------------

             Summary: Support updates at specific time
                 Key: FALCON-238
                 URL: https://issues.apache.org/jira/browse/FALCON-238
             Project: Falcon
          Issue Type: New Feature
            Reporter: Shwetha G S
            Assignee: Shwetha G S


Currently, feed/process update sets end time of coordinator to now and then creates new coord
with start time as now. When updating a process's workflow/lib, its useful to stage an update
with specific timestamp so that all instances before the timestamp use the old lib and instances
after the timestamp use new lib. This is useful to roll-out any application changes

This can be implemented by taking additional timestamp argument in update and honour that
whenever possible. For cases where this can't be honoured, return the update timestamp always
so that user is ware of when the new lib is used
