| ### Using the `HiveFederatedCatalogFactory` |
| |
| This `HiveFederatedCatalogFactory` module is an independent compilation unit and will be built into the Polaris binary only when the following flag is set in the gradle.properties file: |
| ``` |
| NonRESTCatalogs=HIVE,<alternates> |
| ``` |
| |
| The other option is to pass it as an argument to the gradle JVM as follows: |
| ``` |
| ./gradlew build -DNonRESTCatalogs=HIVE |
| ``` |
| |
| Without this flag, the Hive factory won't be compiled into Polaris and therefore Polaris will not load the class at runtime, throwing an unsupported exception for federated catalog calls. |
