Philip Zeyliger commented on IMPALA-6990:
-----------------------------------------

Is this user-visible? Let's say that a user had impala-shell working on RH6 or 
RH7 before. Does it still work? Does it work when using the same 
{{ssl-minimum-version}} and {{ssl-cipher-list}} flags?

I think this test is saying that these flags don't work for the Python shipped 
in RH7. I suspect they didn't work before either: did they somehow work before? 
Surely before the Thrift change, we were using the same RH image?

Once we've figured this out, I think the easier thing to do is to disable the 
test when using a too-old version of Python. We already have a "skip if legacy 
SSL" flag on the test; this is just one more skip if. We still want to run the 
test for Ubuntu16 or whatever. I think we can assume that the Python running 
the test and the python running impala-shell are the same for our purposes.

Is there a weaker test that we'd want to add?
