These are versions I have installed:

thrift==0.9.3
thrift-sasl==0.3.0
thriftpy==0.3.9
impyla==0.14.0

The dependencies below work for me in docker container to initialize hive and impala client both.

system version

Python 3.6.8 Debian GNU/Linux 9 (stretch)

requirements.txt

impyla==0.15.0
sasl==0.2.1
thrift_sasl==0.2.1
thriftpy==0.3.9
thriftpy2==0.4.0

apt packages

sudo apt-get install libsasl2-dev libsasl2-2 libsasl2-modules-gssapi-mit

yes, this works, thanks! and also, suddenly, i needed sasl==0.2.1. And then, all together, it works.
