Hi,
I just tried upgrading a perfectly working Cassandra 0.6.3 to Cassandra 0.7
and am finding that even after re-generating the erlang thrift bindings that
I am unable to perform any operation.
I can get a connection but if I try to login or set the keyspace I get a
report from the erlang bindings to say that the connection is closed.
I then tried upgrading to a later version of thrift but still get the same
error.
e.g.
(zotonic3...@127.0.0.1)1> thrift_client:start_link("localhost", 9160,
cassandra_thrift).
{ok,<0.327.0>}
(zotonic3...@127.0.0.1)2> {ok,C}=thrift_client:start_link("localhost", 9160,
cassandra_thrift).
{ok,<0.358.0>}
(zotonic3...@127.0.0.1)3> thrift_client:call( C, set_keyspace, [ <<"Test">>
]).

The cassandra log seems to indicate that a connection has been made
(although thats only apparent by a TRACE log message saying that a logout
has been done).
The cassandra-cli program is able to connect and function normally so I can
only assume that there is a problem with the erlang bindings.
Has anyone else had any success using 0.7 from Erlang ?
