Could we move this change to HiveClientImpl.scala#L1043?

Option(table.owner).filter(_.nonEmpty).orElse(userName).foreach(hiveTable.setOwner)

It sounds like a bigger deal than it is. Indeed, I am going to add alter table owner syntax, which may make this kind of change back and forth

Thank you @HyukjinKwon Fixed by #26160.

val hiveTable = toHiveTable(
table.copy(properties = table.ignoredProperties ++ table.properties), Some(userName))
table.copy(properties = table.ignoredProperties ++ table.properties), Some(owner))
// Do not use `table.qualifiedName` here because this may be a rename
val qualifiedTableName = s"$dbName.$tableName"
shim.alterTable(client, qualifiedTableName, hiveTable)
