[Iplant-api-dev] Problems submitting fAPI jobs

[Rion Dooley]

Hi Doug,

It’s really important that, when building your apps, you have a mechanism for retrying failed jobs. Often times, the underlying systems and networks will do weird things. That’s nothing Foundation can predict or avoid. While it does retry several times on it’s own, if a head node goes down, gets overloaded, or the network just does weird things while it’s retrying, the job will fail. It’s up to you, as a developer, to retry jobs that inexplicably fail as part of your normal submission workflow.

On another note, I’ve noticed that a lot of appellations are submitting “test” jobs several times a hour. Not only is this a horrible use of public resources, it’s also ineffective because they don’t actually test anything other than whether the API is responsive, which the past few months has been well over 99% of the time. It would be better to ping the system directly (not recommended), or use Agave’s monitoring service<http://agaveapi.co/live-docs/#!/monitors> to make this check for you. If you are worried about the actual API status, then you can subscribe for notifications from the Agave Status page, hosted by status.io<http://status.io> at  http://status.agaveapi.co. The status page is guaranteed 100% uptime and accurately reflects current system statuses.

I'm noticing problems submitting jobs to fAPI as djennewe (job id 57821).  Job submission seems to fail with a Java io exception message like "Failed to submit job 57821: java.io.IOException: Error completing remote execution after: "  Jobs had been working normally earlier today.
