Simialr. I was expecting something like:
```python
session1 = SparkSession.builder.config("key1", "value1").getOrCreate()
session2 = SparkSession.builder.config("key2", "value2").getOrCreate()
assert(session2 == SparkSession.getActiveSession())
session1.createDataFrame([(1, 'Alice')], ['age', 'name'])
assert(session1 == SparkSession.getActiveSession())
```
does this work?
