Colin Patrick McCabe commented on HDFS-4533:
--------------------------------------------
I ran the command with the patch, and {{./sbin/start-dfs.sh -crazygonuts}} was
rejected. However, {{./sbin/start-dfs.sh -upgrade -crazygonuts}} was accepted
without a visible error message.
Given that the obvious error handling cases are covered, I withdraw my earlier
objection. I still think we should add a way to pass arguments to the other
daemons, but I suppose that can be added in a separate JIRA when we actually
need it.
> start-dfs.sh ignored additional parameters besides -upgrade
