Thanks, Mohammad. That's what I thought, but I just wanted to make sure I 
wasn't missing something.

In terms of the behavior, I would think that the "trigger" times when in 
NO_PAST_EXECUTION mode (bad name maybe, but you get the idea) would be a subset 
of those that would occur in the current (DEFAULT_EXECUTION) mode, irrespective 
of the submit time. So, continuing with the example that I included in my 
original email with submit time of 2013-11-04T12:30Z, the fire times would be:

DEFAULT_EXECUTION               NO_PAST_EXECUTION

I have not run this example in the current Coordinator, so I'm not sure about 
the first and last times (whether they fire or not), but I think you get the 
idea.

Thanks again,
Richard.

Subject: Re: Stopping Oozie Coordinator from running in the past

Hi Ross,
Currently there is no way of doing that.
The same discussion came few times before. I think Oozie should provide an easy 
way to start coordinator from the current time. However, when we talked 
previously, it was not easy to determine granularity of current time. For 
example, if the current time is  :"2013-11-04 10:03Z" and the frequency is 5 
minutes. What should be the action nominal time. Will it be 10:03, 10:08 or 
10:13 etc. OR it will 10:00, 10:05, 10:10. The reason is : based on starttime 
the value of current() and latest() are calculated.

Having said that, we should start this discussion  and come to an agreement. 
Any volunteer?

Regards,
Mohammad

Hey Mona:

Thanks for your reply, and I agree that this should be parameterized (this was 
just an example). But I still have to make sure that the value of the 
parameters is correct and not in the past. In my mind I have just pushed the 
problem to another location. What I want to know is if there is a setting for 
the Coordinator that will make it so that I don't have to worry about this.

Thanks,
Richard.

Hi Richard,

Why not parameterize the coordinator "start" time? This start time should be 
when you wish the first instance to run.

E.g. <coordinator-app name="test-coord"
        frequency="${coord:hours(1)}"
        start=${my_start_time}
        end="2013-11-04T24:00Z">
