exactly did you change in* core-site.xml *and *yarn-site.xml.*

Hello Everyone,
I have been trying to run *koalas* on both pyspark and pyCharm IDE.
When I run
df = koalas.DataFrame({‘x’: [1, 2], ‘y’: [3, 4], ‘z’: [5, 6]})
df.head(5)
I don't get the data back instead, I get an object.
I thought df.head can be used to achieve this.
Can anyone guide me on
Couple of questions regarding udfs:
1) Is there a way to get all the registered UDFs in spark scala?
I couldn’t find any straight forward api. But found a pattern to get all the
registered udfs.
Spark.catalog.listfunctions.filter(_.className == null).collect
This does the trick but not sure it
