Hmm, I think there is an error because in your mixing of named and
positional arguments, the positional arguments are not the prefix of argument
lists.
I.e., the compilation error:
checkRelation(table, isDataSourceTable = true, "parquet")
Should be fixed by:
checkRelation(table, isDataSourceTable = true, format = "parquet")
