Gengliang Wang 36a2e6371b [SPARK-26716][SQL] FileFormat: the supported types of read/write should be consistent ... ## What changes were proposed in this pull request? 1. Remove parameter `isReadPath`. The supported types of read/write should be the same. 2. Disallow reading `NullType` for ORC data source. In #21667 and #21389, it was supposed that ORC supports reading `NullType`, but can't write it. This doesn't make sense. I read docs and did some tests. ORC doesn't support `NullType`. ## How was this patch tested? Unit tset Closes #23639 from gengliangwang/supportDataType.
