Apache Aurora cron jobs are not scheduled

Question

I setup a Mesos cluster which runs Apache Aurora framework, and i registered 100 cron jobs which run every min on a 5 slave machine pool. I found after scheduled 100 times, the cron jobs stacked in "PENDING" state. May i ask what kind of logs i can inspect and what is the possible problem ?

Answer 1

It could be a couple of things:

• Do you still have sufficient resources in your cluster?
• Are those resources offered to Aurora? Or maybe only to another framework?
• Do you have any task constraints that prevent your tasks from being scheduled?

Possible information source:

• What does the tooltip or the expanded status say on the UI? (as shown in the screenshot)
• The Aurora scheduler has log files. However normally those are not needed for an end user to figure out why stuff is stuck in pending.

In case you are stuck here, it would probably be the best to drop by in the #aurora IRC channel on freenode.
