> If the yarn configuration does not explicitly specify a value for the 
> yarn.server.nodemanager.log.dir property, container allocation will fail on 
> the NodeManager w/an NPE when the LocalDirAllocator goes to create the temp 
> directory. In most of the code, we handle this by defaulting to /tmp/logs, 
> but we cannot do this in the LocalDirAllocator context, so we need to set the 
> default value explicitly in the Configuration.
> Marking this as major b/c it's annoying to bump into it when you're getting 
> your first MRv2 cluster up and running. :)
