How to find the Heron scheduler files when deployed it on Aurora and Mesos?

Question

I can't find the heron log files when it was deployed on Aurora and Mesos. The aurora-scheduler ui showd as follows:

And In the log-files directory, there is no scheduler related log. So do you have any ideas about this question? Where can I find the heron scheduler log files?

Answer 1

Heron Aurora scheduler is executed on your local host when a topology is submitted. It prepares everything, update the state, and then invoke the aurora client. If you add --verbose to your submit command, you can see a lot of logs there. E.g.

[2018-06-28 09:42:35 -0700] [INFO] org.apache.heron.scheduler.aurora.AuroraLauncher: Launching topology in aurora ... ... [2018-06-28 09:42:35 -0700] [FINE] org.apache.heron.spi.utils.ShellUtils: Running synced process: ``aurora job create --wait-until RUNNING --bind

There's no log regarding the scheduling event saved once the topology starts to running inside aurora containers.
