Hey Everyone,
We just had 3 seats open to the Cassandra Developer course in Redwood City on 4/30/14. If you are interested in attending, please register at the link below before they sell out: http://www.datastax.com/what-we-offer/products-services/training Steph *From:* Chris Lohfink [mailto:clohf...@blackbirdit.com] *Sent:* Thursday, April 24, 2014 8:39 AM *To:* user@cassandra.apache.org *Subject:* Re: nodetool hangs The way RMI (which JMX uses, which is what nodetool uses) works is it will first connect, then send a address/port back over the wire for it to make a new 2nd connection too. This will be potentially to a different address then 127.0.0.1 (can override with -Djava.rmi.server.hostname=<public name> in /etc/cassandra/cassandra-env.sh) and a random port. Likely the 2nd connection is whats timing out. JMX makes firewalls and sysadmins very frustrated :) --- Chris Lohfink On Apr 24, 2014, at 7:05 AM, Jacob Rhoden <jacob.rho...@me.com> wrote: I’ve done an install on an amazon instance, and for some strange reason I can telnet to the JMX port, but node tool just hangs and doesn’t do anything. I am hoping I’m overlooking something simple that someone could help me point out? Thanks (: cassandra@t1:/cassandra/db$ telnet 127.0.0.1 7199 Trying 127.0.0.1... Connected to 127.0.0.1.

(cqlsh works fine, its just nodetool thats giving me the headache) Thanks, Jacob
