Description

Yarn does not complain while passing an invalid hostname like 'invalidhost.com' inside include/exclude node file. (specified by 'yarn.resourcemanager.nodes.include-path' or 'yarn.resourcemanager.nodes.exclude-path').

Need to add a mechanism to check the validity of the hostname before including or excluding from cluster. It should throw an error / exception while adding/removing an invalid node.
