Anyone else having random errors show up in notebooks?
Hello arpost
Thank you for reaching out to Microsoft Community Forum.The error message
Py4JJavaError: An error occurred while calling...java.lang.IllegalStateException: SparkSession should only be created and accessed on the driver usually indicates an attempt to create or access a SparkSession on a worker node instead of the driver node.
- Ensure the SparkSession is created only once and on the driver node. Avoid creating it inside functions executed on worker nodes.
- Verify that code involving SparkSession operations is not executed within transformations or actions on worker nodes, such as map, filter, or other RDD operations.
- Ensure the SparkSession is not referenced as a global variable inside functions on worker nodes.
If the issue persists, consider sharing the specific code snippet causing the error for a detailed analysis.
