Add Python 3.9 support to Hive

[potiuk]

Hive support for Python 3.9 has been removed in #15515 but cloudera
released new ssl 0.3.1 library version to support it and we should
be able to get Hive provider working for Python 3.9 too.

Fixes: #21891

I would love this one merged before I release a new wave of providers for Feb

I see dropbox/PyHive#380 is still open. What changed to make this viable?

Yeah, I thought the same initially and commented the same - but I looked closer - see #21891 discussion. Rather than PyHive switching to another implementation (pure-sasl based) cloudera released the sasl library with 3.9 support - this was the 5 years old library I mentioned in the original PR https://pypi.org/project/sasl/#history

I am going to close dropbox/PyHive#380 as soon as we merge this one.

Closed/Reopened to ACTUALLY run Python 3.9 tests (with full tests needed label :)

[potiuk]

And 🤦 I also removed the skipIfs to actually RUN the tests on Python 3.9 :D

Ah, so the 0.3 series of sasl supports 3.9, solving our issue.

Perhaps it’d be worthwhile to add some additional specifiers to describe this? e.g.

# Some comment explaining 3.0 added 3.9 support...
sasl; python_version<"3.9"
sasl>=3.0; python_version>="3.9"

Good idea. I prefer not to complicate our setup if not needed sasl is a very specific library and pragmatically speaking anyone installing hive provider on Python 3.9 wll get latest (0.3.1) version installed. But yeah that might be a good idea as there might be some cases where someone has an older version of sasl library installed.

Adding it.

Added it now @uranusjr ! Thanks for pointing it out ! I actually made it >=3.0.1 as apparently 3.0.1 0.3.1 was released a day after 3.0.0 0.3.0 (after 5 years) and this might only mean one thing even if 3.0.0 0.3.0 is not yanked :)

[potiuk]

🤦 🤦 🤦 0.3.1 not 3.0.1 @potiuk. Try to copy&paste next time :D
