Subject Re: Problem in using PHPcassa: Uncaught exception 'Exception' with message 'Could not connect to a cassandra server'
Date Mon, 20 Dec 2010 16:21:35 GMT
Keyspace1 is included by default in the cassandra.yaml file and I
imported the schema before running the php script
so I hope that is not the problem..

I am now too much frustrated with this problem..:(  and this is just
the beginning of my Cassandra experiments
