Getting Error : Could Not Connect to Fire at Localhost (PySpark Engine)

Setup & Configuration
1

When opening any PySpark node I get the following error:

Could not connect to fire at localhost.

Solution :

  • The reason for it is that the Sparkflows helper PySpark process is not starting.

    Check out the log files namely, fireserver.log and pyspark.log for errors. They are written in the install directory.

  • Please check if any compatiblity issue for Spark and PySparkling Version.

    Please ensure that the application is started from the appropriate Python environment, with all the required Python dependencies installed.

Refer Below document for more details : Installation — Sparkflows 3.0 documentation
