Chun Chen commented on YARN-1983:
---------------------------------
Attach a patch which creates a CompositeContainerExecutor to implement this.
The patch allows apps to specify container executor class in
ContainerLaunchContext. Also changes
${yarn.nodemanager.container-executor.class} to allow specify a comma separated
list of container executor class and adds a new configuration
${yarn.nodemanager.default.container-executor.class}, the default container
executor to execute(launch) the containers when submit containers without
specify container executor.
> Support heterogeneous container types at runtime on YARN

> 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.
