Aaron T. Myers commented on MAPREDUCE-2644:
-------------------------------------------
One option would be to change {{LocalDirAllocator}} to accept a default value
for the config key you pass in. Another (probably better) option would be to
just add a default value to the {{mapred-default.xml}} file, which gets loaded
any time an MR config object is created.

> 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. :)
