how to submit a task everywhere, but here

matlach Oct 18, 2012 9:16 PM

Hello everyone,

I was looking at the DistributedExecutorService interface and the DefaultExecutorService implementation and I was wondering if there was any way to submit a task everywhere but here (all the other nodes) using the distributed execution framework.

Basically what I want to achieve here is to execute two different runnables in parallel :

the first runnable would be executed locally, while

the second runnable would be executed on all the other nodes in the cluster.

In the end I guess I could extends the DefaultExecutorService though I was wondering if there was anything else I'm not thinking that could be more effective?

maybe to have my runnable be aware of it is origin so then I could submit everywhere?.

Big thanks,

Not at this time, I think your best bet is to extend DefaultExecutorService!

Thanks Vladimir for the anwser.

Do you plan for the 5.2.0.Final release to provide a new interface for the DistributedExecutorService ?

I think it would be nice to be able to just add a submit(Address... addresses, Callable task) method.
That way all the address filtering (submit on the same machine, site, everywhere, everywhere but here, etc.) could be easily achieved.
Maybe some method, like the one I just proposed, could be isolated in an AdvancedDistributedExecutorService, a bit like the AdvancedCache interface ?

What do you think about that ?

Hey Mathieu,

Yeah, I think we could add:

<T> List<Future<T>> submitEverywhere(Callable<T> task, Address...);

Please open a JIRA issue and we'll see to squeeze it in 5.2.

Regards,
Vladimir

P.S In Jira description make a case for this feature as it will be easier to push it in 5.2 final.
