----------------------------------------------------
Thanks for filing this. I ran into the same issue but was lazy enough not to
create it. Essentially what happens for me is that on a small enough cluster
(single node actually), if all nodes are blacklisted by the AM, it will just
keep getting containers and wasting them.
> Support AM specific blacklisting of nodes on the RM

> The AM blacklists certain nodes due to task failures but the RM does not know
> of this and can allocate blacklisted nodes to the AM again and again.
> RM should support a protocol that allows AM to inform the RM of nodes that it
> should not allocate to it.
