Py4JError:org.apache.flink.table.catalog.hive.HiveCatalog在JVM中不存在

我正在尝试从以下url运行flink目录示例：

从pyflink.table导入*
从pyflink.table.catalog导入HiveCatalog、CatalogDatabase、ObjectPath、CatalogBaseTable
从pyflink.table.descriptor导入卡夫卡
settings=EnvironmentSettings.new_instance（）。在批处理模式（）下。使用\u blink\u planner（）。build（）
t_env=BatchTableEnvironment.create（环境设置=设置）
catalog=HiveCatalog（“myhive”，None，”）

但我有一些错误：

ERROR:root:Exception while sending command.

During handling of the above exception, another exception occurred:
