Issue upgrading to Spark 2.3.1 (Maintenance Release)

[Aakash Basu]

Hi,

Downloaded the latest Spark version because the of the fix for "ERROR
AsyncEventQueue:70 - Dropping event from queue appStatus."

After setting environment variables and running the same code in PyCharm,
I'm getting this error, which I can't find a solution of.

Exception in thread "main" java.util.NoSuchElementException: key not found:

Any help?
