@Test
public void testUnsetCatalogWithShowFunctions() throws Exception {
TableEnvironment tEnv = TableEnvironment.create(ENVIRONMENT_SETTINGS);
tEnv.useCatalog(null);
TableResult table = tEnv.executeSql("SHOW FUNCTIONS");
final List<Row> functions =

// check it has some built-in functions
assertThat(functions).hasSizeGreaterThan(0);
}
