@Flachboard84  - could you please try the below code ?

library(SparkR, include.only=c('read.parquet', 'collect'))

sparkR.session() is not required on the databricks notebook. This should be handled automatically.

Reference: https://docs.databricks.com/en/sparkr/overview.html

Thanks for the reply!

Now I'm getting this:

Warning in sparkR.callJMethod(SparkR:::getSparkContext(), "setLocalProperty", : could not find function "sparkR.callJMethod"

@Flachboard84  - could you please share the associated code?

It happens with any code; even something as simple as...

x <- 2 + 2
