> Currently, we default to enabling the CombineFileInputFormat settings for any extensions
of FileSourceImpl b/c it tends to improve performance for common file formats like text, sequence
files, and Avro files. However, this default has caused problems for formats like Parquet
and for custom file formats that have complex split logic.
> This JIRA is to track modifying the default combine file settings in at least some contexts,
such as with From.formattedFile for custom input formats.
