Jason Brown commented on CASSANDRA-7716:
----------------------------------------
one additional thing to add might be if you have a misformatting (or just
outright incorrect value) in the columnspec section, current stress immediately
shut down, with no error. It might be nice to indicate to the user that
something is wrong with their yaml, extra credit if we can tell them what it
is.
> cassandra-stress: provide better error messages

> Just tried new stress tool.
> It would be great if the stress tool gives better error messages by telling
> the user what option or config parameter/value caused an error.
> YAML parse errors are meaningful (gives code snippets etc).
> Examples are:
> {noformat}
> WARN 16:59:39 Setting caching options with deprecated syntax.
