AssertionError: Thrift API version mismatch. (Client: 12, Server: 13)

I am installing Twissandra - a python example on top of Cassandra. Instructions Here. After successfully compiling and building all dependencies on Lubuntu 10.04 (with Thrift 4.0 and then tried with 2.0)--when I run the last step with the webserver--it crashes and posts this Apache Thrift error:

AssertionError: Thrift API version mismatch. (Client: 12, Server: 13)

Is this a thrift problem (4.0) and or a Cassandra problem (7.0 beta)? Cassandra reports in its logs

INFO 23:52:01,487 Cassandra version: 0.7.0-beta1-SNAPSHOT INFO 23:52:01,487 Thrift API version: 13.0.0

A: 

A client problem. Your client is not up-to-date.

You mean the Cassandra Client? Is the Cassandra client installed seperate from what is in the git repo?

actaully, I don't know how the python client is handled. The Java client is obtained from the cassandra build, but for python it seems different

twissandra has not yet been updated for Cassandra 0.7. Use 0.6.5

I had this problem too just a few days ago. If you update both thrift and pycassa it will work, they're both at 15 now I believe.

pycassa is now on version 16 - but I think you are on the right track so I moved my accepted answer here
