Subject Re: Running java stress tests
Date Mon, 07 Nov 2011 20:44:19 GMT
I managed to fix my own problem.

I had "rpc_address" set to localhost. Running an strace on the stress
command shows this attempt to bind to an IPV6 address. Leaving this blank
fixes the problem since host resolution works fine on my cluster.

Thanks,

Joe
