And I try to change the pydruid version on the requirements-dev.txt from 0.5.9 to 0.5.8 and this bugs is eliminated.

[villebro]

Thanks @essajiwa , this is a known issue with pydruid on python 3.7, see druid-io/pydruid#198 .

FYI @etr2460 @john-bodley : To ensure a smooth transition to 3.7 and beyond, we should probably fix this bug in the pydruid build first.
