Requeue task from node
« on: March 18, 2014, 01:45:26 PM »

Hello team,

Is it possible to requeue task from node? For example, during execution on node we get error and decide to repeat this task on another node (if possible, without client notification). Will be good to specify max repeats count.

Thanks,
Emin

Hello Emin,

This feature is not available yet, but it will be in JPPF 4.1, see JPPF-233 Ability for a task to schedule itself for resubmission

Hi Laurent,

Thanks, will be happy to look on it.

As I can see you decided to use job SLA for it. Do you have plans to introduce task SLA? I think that for 99% of JPPF users MaxTaskResubmits for the tasks in one job will be the same but I can imagine situation that in one job for some tasks we do not require resubmition, for some - resubmit 2 times, for other - resubmit 5 times.

Thanks,
Emin

Hi Emin,

Yes, a task SLA is a very good idea, I registered a feature request for this: JPPF-235 Task SLA.
I targeted it for v4.2, as this represents a large redesign/refactoring effort which will not fit realistically in our schedule for 4.1.

Sincerely,
-Laurent
