AM timeout on RM failure?

[Karthik Kambatla]

Hi YARN devs,

I am working on the ZKRMStateStore, and had a very basic question - on RM
failure, how long does the AM fail before crashing, or more importantly
what controls it.

Looking into the code, I see the following two parameters:

   1. yarn.app.mapreduce.am.scheduler.connection.wait.interval-ms - set to
   1 min
   2. Fix configs
   
yarn.resourcemanager.resourcemanager.connect.{max.wait.secs|retry_interval.secs}
   - set by default to 15 mins and 30 seconds respectively

The AM crashes only after 20 minutes.

Are there any other configs that influence this?

Thanks
Karthik
