Subject Re: Newbie question about connecting to a cassandra server from another server using Fauna
Date Mon, 06 Dec 2010 21:23:37 GMT
I've found the solution, thanks for the help, I needed to change the addresses on the storage-conf.xml
both ListenAddress and  ThriftAddress to the address of the server itself. Sorry about the
snippet being incomplete btw
