Example 36 with ISchema

use of org.apache.hadoop.hive.metastore.api.ISchema in project hive by apache.

the class TestObjectStoreSchemaMethods method schemaAlreadyExists.

@Test(expected = AlreadyExistsException.class)
public void schemaAlreadyExists() throws TException {
    Database db = createUniqueDatabaseForTest();
    String schemaName = "schema2";
    ISchema schema = new ISchemaBuilder().setSchemaType(SchemaType.HIVE).setName(schemaName).inDb(db).build();
    objectStore.createISchema(schema);
    schema = objectStore.getISchema(new ISchemaName(db.getCatalogName(), db.getName(), schemaName));
    Assert.assertNotNull(schema);
    Assert.assertEquals(SchemaType.HIVE, schema.getSchemaType());
    Assert.assertEquals(schemaName, schema.getName());
    Assert.assertEquals(SchemaCompatibility.BACKWARD, schema.getCompatibility());
    Assert.assertEquals(SchemaValidation.ALL, schema.getValidationLevel());
    Assert.assertTrue(schema.isCanEvolve());
    // This second attempt to create it should throw
    objectStore.createISchema(schema);
}

Example 37 with ISchema
