Subject: ApplicationMaster's logs are not available


I'm writing my own AM, but YARN collects and shows no logs for its container whatsoever. My
AM runs forever and I would like to debug it, but without logs I just can't do it. My AM uses
org.slf4j.Logger for logging. Other applications, like MR and Spark logs fine. Is there any
option that I need to set explicitly to enable logging? I've tried to fetch logs with and
without log-aggregation-enable, but without success.

I would appreciate any tips regarding this.
