Aleksey Yeschenko commented on CASSANDRA-10142:
-----------------------------------------------

[~bdeggleston] thanks for finding the reason. This needs to be fixed in the driver, for 2.1 and 2.2 C* users. However, for 3.0, after some discussion, we decided to consider removing support for v1 and v2 protocols (see CASSANDRA-10146), so marking this issue as Won't Fix, unless someone objects to that decision.

> When trying to connect with the Python driver to a cluster running trunk, the connection fails with a {{NoHostAvailable}} exception if the protocol version is set to 1 or 2.
> The attached script reproduces the error and demonstrates that the connection works if the protocol version is 3 or 4.
