Python Standard Library contains built-in modules (written in C) that provide access to system functionality such as file I/O that would otherwise be inaccessible to Python programmers, as well as modules written in Python that provide standardized solutions for many problems that occur in everyday programming. After setting these, you should not see No module named pyspark while importing PySpark in Python. Problem: While running PySpark application through spark-submit, Spyder or even from PySpark shell I am getting Pyspark: Exception: Java gateway process exited before sending the driver its port number. We shall save the new array into the new_array variable. Alternatively, it seems like it might be an issue with the logs. Do you know why that is? The common input-output operations are opening a file or a directory, executing a print statement, etc. Now set the SPARK_HOME & PYTHONPATH according to your installation, For my articles, I run my PySpark programs in Linux, Mac and Windows hence I will show what configurations I have for each. To solve the error, we can open the file in w+ mode.
