Description

 CatalogServiceCatalog.setFileMetadataFromFS() only fills the field "file_descriptors" and leaves "insert_file_descriptors" and "delete_file_descriptors" as null.
 
This leads to a NullPointerException in CatalogdMetaProvider.loadPartitionsFromCatalogd().
 
The fix must fill properly all the file descriptor fields.
