What does the error message "JavaPackage object is not callable" mean in the context of AWS Glue and Pyspark?

edit

The error message "JavaPackage object is not callable" in the context of AWS Glue and Pyspark usually means that the Pyspark code is trying to call a Java package as a function or method, but the Java package is not callable in that manner. This could happen if the Pyspark code is not importing the Java package correctly, or if the specific function or method being called is not available in the Java package. To resolve the issue, the Pyspark code should be reviewed to ensure that the proper Java packages and functions are being imported and called correctly.
