--------------------------------
Looks like you are correct. At some point we need to profile the memory of the AM and see
if we need to fix something.
> AMContainerImpl are stored even after container has completed

> For a long running job thats allocated 100's of 1000's of containers this can be a memory
usage issue. Even if AMContainerImpls are small they contain full copies of container launch
context objects that look like heavy weights with multiple maps of local resources, env etc.
