Is it possible that you are somehow using the 0.7 generated cassandra module, perhaps from some previous installation of a client library? In 0.7, insert takes only 5 arguments.
Also, is there any particular reason that you are using raw Thrift and not a high level client like pycassa, telephus, etc? - Tyler On Wed, Sep 22, 2010 at 9:32 PM, Shashank Tiwari <tsha...@gmail.com> wrote: > Jeremy and Aaron, > Thanks for your help. > > I had already installed Thrift on my Snow Leopard so I thought running > *thrift > -gen cassandra.thrift* file would work.
