Isn't this in the base class?

[nastra]

it's not. We only throw for ViewMetadata but not for TableMetadata in https://github.com/apache/iceberg/pull/8831/files#diff-3594848799883f9d669511640aadba2b625ce3e07b93a2ae211fcc2bb999e0aaR28, but we could change that. Let me know if you'd like me to make that change

I went ahead and moved this to the base class, so that we're in line with MetadataUpdate:

iceberg/core/src/main/java/org/apache/iceberg/MetadataUpdate.java

Lines 31 to 39 in d9eb937

	default void applyTo(TableMetadata.Builder metadataBuilder) {
	throw new UnsupportedOperationException(
	String.format("Cannot apply update %s to a table", this.getClass().getSimpleName()));
	}
	default void applyTo(ViewMetadata.Builder viewMetadataBuilder) {
	throw new UnsupportedOperationException(
	String.format("Cannot apply update %s to a view", this.getClass().getSimpleName()));
	}

Why is this separate? I thought that we were just going to add assert-view-uuid to the other. I don't like having separate View and Table requirements since we use the same ones in most places.

I followed up with @nastra offline. Since the only requirement for views is assert-view-uuid and we don't want to change or reuse assert-table-uuid, it does make sense to have a separate set of requirements.

+1 when tests are passing. Thanks for making the refactor to move methods into the base class.
