When you load a multipart Parquet dataset (such as a directory that contains part1.parquet, part2.parquet, and so on files), the load might fail. This issue occurs if ls -ltr on the file system and PROC CASUTIL LIST FILES return the files out of order. Here is an example of the files being returned out of order: part5.parquet, part1.parquet, part2.parquet, and so on.

The hot fix ensures that Parquet files are being processed in the correct order regardless of access method.
