In T222941 we are testing python-kafka 1.4.7 on eventlog1002, that seems working well. The new version doesn't need the custom patch that we added to the deb since it is already included, so it would be great to upgrade all consumers of the package:
https://debmonitor.wikimedia.org/packages/python-kafka
The Analytics hosts are the predominant set of hosts to upgrade, but there are also webperf ones that @Gilles upgraded the last time (T221848). It would also be great to know what services are relying on python-kafka (as opposed to python3-kafka) since it would be great to move to python3 everywhere (see https://www.python.org/doc/sunset-python-2/).
Eventlogging is moving to Python3 in T233231.
