Chris Douglas commented on YARN-1983:
-------------------------------------
As in YARN-2718: can't this be implemented as a composite CE, rather than
changing the CLC? Managing versions of the CE, selecting a compatible CE,
matching in the scheduler, etc. will require more than the classname to match.
Configuring multiple CEs covers some useful cases, but if a composite CE is
sufficient to experiment, then we can avoid a kludge in the protocol.

> 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.
