> 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"
