### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Paimon version 1.3.1 ### Compute Engine Flink 2.1.1. ### Minimal reproduce step using Paimon Java API, try to list tables in existing Iceberg REST catalog namespace: ```scala //> using dep "org.apache.paimon:paimon-api:1.3.1" import org.apache.paimon.options.Options import org.apache.paimon.rest.RESTApi import java.util.List import org.apache.paimon.options.CatalogOptions.WAREHOUSE import org.apache.paimon.rest.RESTCatalogOptions.DLF_ACCESS_KEY_ID import org.apache.paimon.rest.RESTCatalogOptions.DLF_ACCESS_KEY_SECRET import org.apache.paimon.rest.RESTCatalogOptions.TOKEN import org.apache.paimon.rest.RESTCatalogOptions.TOKEN_PROVIDER import org.apache.paimon.rest.RESTCatalogOptions.URI def setBearToken(options: Options) = options.set(TOKEN_PROVIDER, "bear") options.set(TOKEN, "<token>") @main def testCatalog = val options = Options() options.set(URI, "http://your-url-here/iceberg/";) options.set(WAREHOUSE, "nessie_warehouse"); setBearToken(options) val api = new RESTApi(options) val tables = api.listTables("default") println(tables) ``` REST requests reach my REST Catalog server, but I see it replies with 404 status ### What doesn't meet your expectations? list tables should return empty list, but it fails with exception: ```scala Exception in thread "main" org.apache.paimon.rest.exceptions.NoSuchResourceException: at org.apache.paimon.rest.DefaultErrorHandler.accept(DefaultErrorHandler.java:62) at org.apache.paimon.rest.DefaultErrorHandler.accept(DefaultErrorHandler.java:35) at org.apache.paimon.rest.HttpClient.exec(HttpClient.java:156) at org.apache.paimon.rest.HttpClient.get(HttpClient.java:81) at org.apache.paimon.rest.RESTApi.lambda$listTables$1(RESTApi.java:328) at org.apache.paimon.rest.RESTApi.listDataFromPageApi(RESTApi.java:1307) at org.apache.paimon.rest.RESTApi.listTables(RESTApi.java:326) at catalogTest$package$.testCatalog(catalogTest.scala:26) at testCatalog.main(catalogTest.scala:19) ``` ### Anything else? It seems Paimon uses "databases" instead of "namespaces" concept. https://iceberg.apache.org/javadoc/latest/org/apache/iceberg/rest/RESTCatalog.html#listNamespaces(org.apache.iceberg.catalog.Namespace) ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
