Review Comment:
Hi @gh-yzou, I did some further investigation on this. I found that even if
we apply a similar fix like in #193, the test from the superclass will still
fail. This is because `write.metadata.path` is only added to `allowedLocations`
for the root namespace — this behavior is by design in Polaris per
[link](https://github.com/apache/polaris/pull/193/files#diff-607cdd8c6ea78443988359e42ffec3091a4c84bc9151575772ee3b90164e03f3R184-R191).
What I mean is that we can specify any location like `file://tmp/`, and it
will be added to `allowedLocations` **only if** we include it when creating the
namespace. So, to make the test pass, we’d need something like the following:
```java
TableIdentifier identifier = TableIdentifier.of("ns", "view");
String location = Paths.get("file://tmp/").toString();
String customLocation = Paths.get("file://tmp/",
"custom-location").toString();
if (requiresNamespaceCreate()) {
catalog()
.createNamespace(
identifier.namespace(),
// Set the custom location in the root namespace
ImmutableMap.of(ViewProperties.WRITE_METADATA_LOCATION,
customLocation));
}
assertThat(catalog().viewExists(identifier)).as("View should not
exist").isFalse();
View view =
catalog()
.buildView(identifier)
.withSchema(SCHEMA)
.withDefaultNamespace(identifier.namespace())
.withDefaultCatalog(catalog().name())
.withQuery("spark", "select * from ns.tbl")
.withProperty(ViewProperties.WRITE_METADATA_LOCATION, customLocation)
.withLocation(location)
.create();
assertThat(view).isNotNull();
assertThat(catalog().viewExists(identifier)).as("View should
exist").isTrue();
assertThat(view.properties()).containsEntry("write.metadata.path",
customLocation);
assertThat(((BaseView) view).operations().current().metadataFileLocation())
.isNotNull()
.startsWith(customLocation);
```
So my conclusion is that the expected behavior of this test is not
applicable to Polaris. I think we can address this in two ways:
1. Use `TempDirFactory` to **change the temp directory** in the superclass
test so that we can always follow upstream changes. Then, **write another**
Polaris-specific test using the above code in another PR with the fix for
createView flow.
2. **Skip** this test in this PR, and use a follow-up PR to **override** it
with Polaris-specific behavior using the code above. This is simpler and more
straightforward, but we won’t catch future changes in the superclass.
