Issue upon Spark Upgrade : key not found: _PYSPARK_DRIVER_CONN_INFO_PATH

Question

Downloaded the latest Spark version because 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: _PYSPARK_DRIVER_CONN_INFO_PATH

Answer 1

i met this question too. The next is what i do, hoping to help you:

1 . find your spark version, my spark's version is 2.4.3;

2 . find your pyspark version, my pyspark,version is 2.2.0;

3 . reinstall your pyspark as same as the spark's version

pip install pyspark==2.4.3

Then everything is ok. Hope to help you.
