Subject [jira] Commented: (CASSANDRA-1453)

Pavel Yaskevich commented on CASSANDRA-1453:

Sorry, if I ask a stupid question but I'm more ruby then python guy:

I have installed thrift exactly as instructions on
said, then I run "ant gen-thrift-py" - all is fine so far, but when I try to do:

`python python contrib/py_stress/` it prints out following:

Traceback (most recent call last):
  File "contrib/py_stress/", line 36, in <module>
    from thrift.transport import TTransport
ImportError: No module named thrift.transport

Maybe you know how to fix that?

> seems to scale poorly past a fairly small number of threads/processes.  (against
a 3-node, RF=1 cluster, I got 3x as much throughput with 4 machines running -t 32,
as running 1 with -t 128.  these were 8-core client machines, and -t 128 reported only 50%
cpu used.)
> since we ship with the thrift java api pre-built, this would also mean not making people
build thrift before using the stress test, which is at best a pain for newcomers and on Windows
a major hurdle.
