Ariel Weisberg commented on CASSANDRA-9019:
-------------------------------------------
I am +1 on returning the string N/A. I am -1 on not logging the exception
somewhere.
It looks like the caller should supply a logger since we access this from
NodeProbe and StatusLogger.
So they would get their expected output along with the error output according
to their logging configuration. It looks like StatusLogger is logging some
statements to stdout and others to a logging framework? Is that intentional?

> system.log, but printed to stderr somehow, it's unclear with all the piping
> dtest and ccm do. I have yet to reproduce the issue.
