I finally grabbed Cassandra off the trunk to make things work so I guess it is 0.7. If I start the same server and connect to it, should things work? I am happy using pycassa or telephus but I had Thrift installed for things beyond Cassandra (for example for Hypertable) and I was hoping that installation would work with multiple products that use Thrift. Now I know it doesn't.
