I am trying to use LocalExecutor instead of the default SequentialExecutor which forces to use a different database then SQLlite.
I wanted to try MySQL, however I am
I was using Python27 all these time, once I update my linux to Python36 all started working. Now I am using Airflow1.10 with Mysql5.6.4
One more thing to keep in mind, browser cookies should be cleared once you update your python version from python27 to python36 for this to work in the UI or else you will see the same error.
Hope this helps someone!
