Cassie + Cassandra thrift versions

[Denny]

Hi all,

I am using Cassie in a project that is also using "org.apache.cassandra" % "cassandra-all" % "1.1.7", which I need to run a MapReduce job over Cassandra. However, it seems like the thrift versions are different, and I am getting an error from Cassie. Cassandra uses libthrift 0.7.0, Cassie uses 0.5.0. If I manually include 0.5.0 Cassie works, but my other Cassandra code stops working.  How do I go about resolving this? I don't mind compiling an including jars myself, but I've spend countless hours debugging this and haven't figured out a way to get both to work.

We're pretty tied to thrift 0.5.0 for now, since that's what finagle depends on.

I see. How difficult is it to build Cassie manually using libthrift 0.7.0? It seems like there is no build script and the maven file includes Twitter-internal dependencies.

Maven is our build system. We're working to fix the problem where it
includes internal dependencies.

Cassie doesn't depend on thrift 0.5.0 directly, it only does it via
finagle. So you'd have to re-built finagle on top of the newer version
of thrift.

As you've noticed thrift introduced backwards-incompatible changes
somewhere between 0.5.0 (this is why we haven't upgraded), so the
re-build might be non-trivial.

Makes sense, thanks for your help, I'll give it a try.
