Chris Douglas commented on YARN-1983:
-------------------------------------

(sorry for the delayed reply; missed this)

bq. I was proposing we continue the same without adding a new CLC field. Are we 
both saying the same thing then?

Yeah, I think we agree. We don't need to extend the CLC definition for this use 
case, because it's less invasive to add a composite CE that can inspect the CLC 
and demux on a set of rules.

I scanned the patch on YARN-1964, and maybe I'm being dense but I couldn't find 
the demux. It does some validation using patterns...

> Different container types (default, LXC, docker, VM box, etc.) have different 
> semantics on isolation of security, namespace/env, performance, etc.
> Per discussions in YARN-1964, we have some good thoughts on supporting 
> different types of containers running on YARN and specified by application at 
> runtime which largely enhance YARN's flexibility to meet heterogenous app's 
> requirement on isolation at runtime.
