As it turns out, the documentation is correct and I was using underscores instead of hyphens.  The correct configuration is:

storage.backend=cassandrathrift

storage.cassandra.frame-size-mb=20

I've been running into the "Frame size (##) larger than max length (15728640)!" on a query and I've tried several options for increasing the value but none seem to be recognized.  Can this value be changed after a graph has been created or does it need to be set before any nodes are added?

In my cassandra.yaml:

thrift_framed_transport_size_in_mb: 20

In my properties file:

storage.cassandra.frame_size_mb=20

I've tried with the following three different settings:

storage.backend=cassandra

storage.backend=cassandrathrift

storage.backend=astyanax

Thanks.
