[core] Ray session conflicts with PyArrow+HDFS

Could you clarify which specific Ray issue you’re facing? There are many possible problems (e.g., cluster connection, dashboard errors, ray.init failures, etc.). Please provide the error message or describe the symptoms so I can assist you accurately.

If you recently encountered a persistent error, clearing Ray’s temporary files (e.g., deleting the %temp%/ray folder on Windows) has resolved some issues for users, especially with ray.init() failures, as discussed in this thread. Would you like more detailed troubleshooting steps?
