-------------------------------
bq. Is it considered backwards compatible to change defaults?
It should be fine, IMO

> 15 minutes timeout for AM/NM connection with RM in non-ha scenario turns out
> to be short in production environment. The suggestion is to increase that
> to 30 min. Also, the retry-interval is set to 30 seconds which appears too
> long. We may reduce that to 10 seconds ?
