Hive connector does not support table locations containing double slashes. On S3 this leads to correctness issues (e.g. INSERT works, but SELECT does not find any data). This commit - restores normalization of implicit table location during CREATE TABLE. There used to be such normalization until 8bd9f75. - rejects explicit table locations containing double slash during `CREATE TABLE .. WITH (external_location = ...)`. Before 8bd9f75 there used to be normalization also during this flow, but rejecting such unsupported locations is deemed more correct.
Configure bucket used in `TestIcebergS3AndGlueMetastoreTest` same way as in other `BaseS3AndGlueMetastoreTest` subclasses. Makes it easier to run tests locally. This also changes `TestIcebergGlueCatalogConnectorSmokeTest` for consistency.
This may be needed when working with MinIO containers where bucket names can be reused. This is not needed when working with real S3 where bucket names are unique. Also, it's unclear whether this is a safe operation when tests execute in parallel.
The `String.contains`-based inclusions/exclusions doesn't allow distinguishing between hypothetical cases like "trailing_slash" and "two_trailing_slashes". This also simplifies generated test locations for schemas. Previously the schema name was formatted twice into the location string.
Remove constructor which doesn't construct the table. Since it was randomizing the name, it couldn't even be used for dropping existing table.
Use try with resources to ensure that test tables are dropped even if an assertion fails.
