When I try to start the RM, I get:

When I try to start the NM, I get:

I poked around a bit. When I jar -tvf my hadoop-yarn-common-0.24.0-SNAPSHOT.jar file, I see
that it has:

Clearly, this is missing the cluster/.keep path, which appears to be required by RM (as it
specifies "cluster" as the webapp name when it starts).

I think that we need to get "cluster" and whatever NM's webapp name is back into the webapps
directory in the jar.
