PySpark Timeout Error - Jupyter

Hi @abhinav & Team,

Facing timeout error while running PySpark RDD code in Jupyter Notebook launched from the Lab.
Please check.

Hi @senthiljdpm,

Your namenode hostname is wrong. Please find the correct hostname in Ambari.

Thanks

I am trying to run the notebook created before your lab upgrade. It would be better if you put a note somewhere in blog explaining the details. If they are already present, please let me know the blog link
