Eli Collins commented on HDFS-3027:
-----------------------------------
Yea, feel free to punt the specific message to another jira. For now we should
at least say "The NameNode has no resources available" to match the code, and
since we're failing to run (vs being low which shouldn't cause us to
necessarily fail the health check).
Also, think you left out the test change from the patch?
