Wenchen Fan 301fb0d723 [SPARK-16731][SQL] use StructType in CatalogTable and remove CatalogColumn ... ## What changes were proposed in this pull request? `StructField` has very similar semantic with `CatalogColumn`, except that `CatalogColumn` use string to express data type. I think it's reasonable to use `StructType` as the `CatalogTable.schema` and remove `CatalogColumn`. ## How was this patch tested? existing tests.
