Description

Currently, `HiveExternalCatalog`'s `createTable` issues the exception if `ignoreIfExists` is true and the table exists. However, this is just a partial handling of `ignoreIfExists`. We can cover the other cases too.

Instead of passing `ignoreIfExists` of CREATE TABLE to Hive metastore, we can handle it in `HiveExternalCatalog`'s `createTable`.
