    Yea, I know the hidden output in the console and I believe that's a known 
issue. In my case, I made such change before - 
https://github.com/apache/spark/pull/20487. Also see the discussion in 
https://github.com/apache/spark/pull/20465.
    
    The thing is, it needs duplicated changes to print out the warnings and 
that's why I have been hesitant to fix related code paths.
    
    Actually, I was thinking we should resemble what we do in `streaming.py` to 
skip the doctests although I haven't taken a close look to check if we can 
control function level yet.
    
    I know we use `# doctest: +SKIP` here and there in particular with Pandas / 
Arrow. I think basically we should remove this and do the same things to test 
them when possible.
    
    I am sure on this too (and told few committers before that I am thinking in 
this way). Let me cc @cloud-fan, @ueshin and @BryanCutler FYI.
    
    For the best, can you investigate and try to explicitly skip some doctests 
conditionally? For console output from our test script, I think we can do this 
separately (but please leave a comment as a todo or JIRA).
