Hi, I’ve got the following exception when running a connected component example in Spark 3.0.0. This code runs without exception in Spark 2.4.
It throws the exception when calling RDDOperationScope.toJson method.
I’m not sure why it throws the execution in Spark 3.0. There is no exception in
Spark 2.4.
Do you have any idea?
I’ve tested ConnectedComponentsExample.
