When using SparkSession.builder.appName in pyspark, what can be done to resolve the FileNotFoundError issue?

edit

There are a few things that can be done to resolve the FileNotFoundError issue when using SparkSession.builder.appName in pyspark:

1. Check the file path: Make sure that the file path specified in the code is correct and the file exists in that location.

2. Specify the file:// protocol: If the file is located on the local file system, add the file:// protocol before the file path.

3. Use Hadoop Distributed File System (HDFS): If the file is located on a Hadoop Distributed File System, use the hdfs:// protocol and make sure that the HDFS is configured correctly.

4. Check the file permissions: Make sure that the user running the pyspark program has read access to the file.

5. Use a fully qualified file path: Use the fully qualified file path including the file name and extension.

6. Set the correct working directory: Set the working directory to the location of the file.
