        ## Dear committer.
        ##
        ## If you ever come here to add the missing isort step here - hear a little warning.
        ##
        ## Initially isort will cause surprising duplicates of urlparse and other urllib related methods.
        ## The urllib imports seem broken for python 2 but they are actually fine due to future
        ## backport aliases installed elsewhere in the code (implicitly) - in 6 places.
        ##
        ## When you decide how to fix it (likely talking to other people in community) and you push
        ## build to CI you will find terrible truth that in Airflow 1.10 modules are so much
        ## cross-dependent, that imports in a number of places have to be done in specific order and
        ## if this is not followed properly, circular imports kick-in and you are doomed.
        ##
        ## Running isort breaks the import House of Cards and there is no easy way to fix it short of
        ## splitting a number of files and probably breaking compatibility.
        ##
        ## Luckily this has been fixed in Airflow 2.0 by proper untangling of the cross-dependencies and
        ## 1.10.* branch is really in maintenance mode, so do not really waste your time here.
        ##
        ## Unless you really want of course. But then either delete this comment or increase the counter
        ## below after you give up.
        ##
        ## Total hours wasted here = 3
