Subject Re: Should session-specific iterators appear on config output?
Date Fri, 22 Jun 2012 21:05:59 GMT
I'd be happy with a "Run 'info -v' for session-specific
configurations." How is that option?

like it would make sense to make it easier to find that information, although I'm not sure
if config is the appropriate place.  The scan iterators do not have to be stored in zookeeper,
so properties like those displayed by config are never created for them.  Perhaps we could
display the scan iterator information you get with "info -v" after the normal config properties
when you use "config".  We could consider synthesizing fake properties for the scan iterators,
but I'd be reluctant to do so.
