Sam Tunnicliffe commented on CASSANDRA-14921:
---------------------------------------------

bq. Can't we just downgrade to 0.9.3 in dtest's requirements.txt?

I seem to recall that there is some other incompatibility between thrift 0.9 
and python3, which was why the dependency got bumped in CASSANDRA-14134. I 
didn't make that change though, so I'll have to check. 

Fixing the issue on our side is fine with me, hence the patch. I just wanted to 
note the presence of the problematic binary so we can maybe remove next time we 
have to do some maintenance on the docker image.

> {{putget_test::TestPutGet::test_wide_slice}} fails on CircleCI since the 
> docker image was updated for CASSANDRA-14713. The reason for this is that the 
> {{fastbinary}} extension used by {{TBinaryProtocolAccelerated}} is not 
> compatible with thrift 0.10.0 (according to [this bug report against 
> Pycassa|https://github.com/pycassa/pycassa/issues/245]). The offending binary 
> is present in the filesystem of the [current docker 
> image|https://hub.docker.com/r/spod/cassandra-testing-ubuntu18-java11/], but 
> wasn't in [the previous image 
> |https://hub.docker.com/r/kjellman/cassandra-test/], which meant that thrift 
> would fallback to the standard protocol implementation (silently).
> As this is the only test which uses {{TBinaryProtocolAccelerated}} it's easy 
> enough to switch it to {{TBinaryProtocol}}, which also fixes things. We might 
> want consider removing the binary next time the image is updated though (cc 
> [[email protected]]).
