Subject [jira] [Commented] (YARN-1983) Support heterogeneous container types at runtime on YARN
Date Fri, 25 Apr 2014 21:13:19 GMT

Junping Du commented on YARN-1983:
----------------------------------

Thanks [~ashahab] for volunteering on this. I think we could discuss more options before quickly
jumping on the effort of extending ContainerRequest in case other people may have some better
ideas. Thoughts?

> 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.
