Oh, I thought 3.6 was already supported (judging by the classifiers) but apparently it is not; #522. This might be a dead cause

[martindurant]

You would need to change python_requires= in setup.py to get the CI to run. The classifiers have not been updates since the last release.

Yes, I am aware. I thought it was the 3.6>= before I made the PR, and I am a bit confused now regarding the official status of support.

[martindurant]

Indeed, it seems a little unfortunate. The selectors are certainly not authoritative, but This could have been a more public discussion. If py36 support is easy, I am not opposed to continuing with it.

Apparently all tests pass, though pyarrow seems to be a bit problematic when installed in <1, is there anything I should be aware when bumping it to 1>=?

[martindurant]

Do you mean pyarrow -> v>1.0? That should be OK. The HDFS implementation is slated to be dropped, but not yet.

[isidentical]

yep

[martindurant]

OK, thanks for doing this - let's keep py36 alive a little longer!

Thanks @martindurant!
