--------------------------------------
+1, lgtm(non-binding). [~sandyr], can you take a look, please?
> allocateContainer() in SchedulerNode needs a clearer LOG.info message

> This bit of code:
> {quote}
> LOG.info("Assigned container " + container.getId() + " of capacity "
> + container.getResource() + " on host " + rmNode.getNodeAddress()
> + ", which currently has " + numContainers + " containers, "
> + getUsedResource() + " used and " + getAvailableResource()
> + " available");
> {quote}
> results in a line like:
> {quote}
> 2014-05-30 16:17:43,573 INFO
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FSSchedulerNode:
> Assigned container container_1400666605555_0009_01_001111 of capacity
> <memory:1536, vCores:1> on host machine.host.domain.com:8041, which currently
> has 18 containers, <memory:27648, vCores:18> used and <memory:3072, vCores:0>
> available
> {quote}
> That message is fine in most cases, but looks pretty bad after the last
> available allocation, since it says something like "vCores:0 available".
> Here is one suggested phrasing
> - "which has 18 containers, <memory:27648, vCores:18> used and
> <memory:3072, vCores:0> available after allocation"
