--------------------------------------

             Summary: When adding variables in Web GUI they are case-insensitive, but everywhere else they are case-sensitive
                 Key: AIRFLOW-1860
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1860
             Project: Apache Airflow
          Issue Type: Bug
          Components: webapp
    Affects Versions: Airflow 1.8
            Reporter: Zelko Nikolic
            Priority: Minor


1. Open Web GUI -> Variables
2. Add a variable named "ABCD" and enter some value for it.
3. Add a variable named "abcd"... you can't. It says that variable already exists. As if variable names are case-insensitive. But they are not.
4. Because if you try accessing the first variable from the code, using Variable.get("abcd"), it will say that variable doesn't exist.

So, from the code variables are case-sensitive, but when Web GUI is adding them, it treats them case-insensitive. To make things even weirder, when you sort the variables by name in Web GUI, it sorts uppercase first, then lowercase. Obviously, even Web GUI isn't consistent with itself, because it's treating them sometimes case-sensitive, sometimes case-insensitive.
