Subject Re: what other ports than 7199 need to be open for nodetool to work?
Date Mon, 26 Mar 2012 19:54:38 GMT
Thanks Nick -- I didn't know about this ticket.  Good to know.

Yes, nodetool doesn't do anything special - but I still wish I could use
nodetool to examine other nodes, instead of having to ssh to other nodes
first and then nodetool each one (i am lazy :-).
