Review Comment:
From the side of Gravitino, it's reasonable to throw `unsupported exception`
but this will cause Trino query failed, because it will try to get view from
Iceberg REST server in analyzer, please refer to
https://github.com/trinodb/trino/blob/master/core/trino-main/src/main/java/io/trino/sql/analyzer/StatementAnalyzer.java#L2279
