Yes thanks, Aniruddha. I was able to dig in the startup scripts and make sure I pass:
-Djava.net.preferIPv4Stack=true That was the key to my issue. -----Original Message----- From: Aniruddha Laud [mailto:[email protected]] Sent: Wednesday, August 29, 2012 11:50 AM To: [email protected] Subject: Re: JRE 7 compatibility? I think the issue is with zookeeper and IPV6, not netty. A simple fix in your situation would be to use 127.0.0.1 instead of localhost (which is resolved to the ipv6 address), or force usage of ipv4 (the way it's done in the startup scripts).
