There are several possible reasons for this error message in PySpark when attempting to read Parquet files, including:
The Parquet file may have been corrupted or formatted incorrectly, making it impossible to read or convert the schema information.
The PySpark version being used may not be compatible with the Parquet file format or schema, causing issues when attempting to read the file.
The Parquet file may have been created with a different encoding or compression scheme than PySpark is expecting, leading to errors or unexpected behavior when attempting to read the file.
The PySpark environment may not have sufficient permissions or access rights to read the Parquet file, resulting in a schema conversion error.
