   Can we disable column pruning when it is Hive ORC table?
   
https://github.com/apache/spark/blob/25e7d1ceee8c9f4ecb4ab796f51e9bcbc0500fae/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/SchemaPruning.scala#L98-L100
   Update `canPruneRelation` to:
   ```scala
     private def canPruneRelation(fsRelation: HadoopFsRelation) = {
       fsRelation.fileFormat match {
         case _: ParquetFileFormat => true
         case _: OrcFileFormat =>
           fsRelation.location match {
             case c: CatalogFileIndex =>
               !c.table.provider.contains(DDLUtils.HIVE_PROVIDER)
             case _ => true
           }
       }
     }
   ```
