Vinod Kumar Vavilapalli commented on YARN-1983:
-----------------------------------------------

We still need a way to demux the executor to support the case of YARN cluster 
with a mix of executors. That'd mean _some_ impact on the CLC, no?

YARN-1964 took the less intrusive way of depending on an env variable in the 
container-launch context, shall we continue doing that? My guess is that 
exposing richer APIs of specific container-types (instead of the process 
oriented CLCs) is better in the long term but too much change in the short term 
as the container-space is still going through very fast changes.

> 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.
