Example 6 with Namespace

use of org.apache.iceberg.catalog.Namespace in project hive by apache.

the class TestHiveCatalog method testCreateNamespace.

@Test
public void testCreateNamespace() throws TException {
    Namespace namespace1 = Namespace.of("noLocation");
    catalog.createNamespace(namespace1, meta);
    Database database1 = metastoreClient.getDatabase(namespace1.toString());

    Assert.assertEquals("There no same location for db and namespace", database1.getLocationUri(), defaultUri(namespace1));
    AssertHelpers.assertThrows("Should fail to create when namespace already exist " + namespace1, AlreadyExistsException.class, "Namespace '" + namespace1 + "' already exists!", () -> {
        catalog.createNamespace(namespace1);
    });
    ImmutableMap newMeta = ImmutableMap.<String, String>builder().putAll(meta).put("location", hiveLocalDir).build();
    Namespace namespace2 = Namespace.of("haveLocation");

    Assert.assertEquals("There no same location for db and namespace", database2.getLocationUri(), hiveLocalDir);
}

Example 7 with Namespace

the class HiveCatalog method listTables.

@Override
public List<TableIdentifier> listTables(Namespace namespace) {
    Preconditions.checkArgument(isValidateNamespace(namespace), "Missing database in namespace: %s", namespace);
    String database = namespace.level(0);
    try {

        LOG.debug("Listing of namespace: {} resulted in the following tables: {}", namespace, tableIdentifiers);
        return tableIdentifiers;
    } catch (UnknownDBException e) {
        throw new NoSuchNamespaceException("Namespace does not exist: %s", namespace);
    } catch (TException e) {

    Assert.assertTrue("Should true to namespace exist", catalog.namespaceExists(namespace));
    Assert.assertTrue("Should false to namespace doesn't exist", !catalog.namespaceExists(Namespace.of("db2", "db2", "ns2")));
}

Example 9 with Namespace

use of org.apache.iceberg.catalog.Namespace in project hive by apache.

the class TestHiveCatalog method testSetNamespaceProperties.
