MiniCluster代码执行过程中报错怎么办？

MiniCluster代码执行过程中报错：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: Defaulting to no-operation (NOP) logger implementation

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Exception in thread "main" java.lang.IllegalStateException: MiniCluster is not yet running.

报错段代码如下：

Configuration config = GlobalConfiguration.loadConfiguration(flinkConfDir);

MiniClusterConfiguration.Builder configBuilder = new MiniClusterConfiguration.Builder();

configBuilder.setConfiguration(config);

MiniCluster miniCluster = new MiniCluster(configBuilder.build());

MiniClusterClient clusterClient = new MiniClusterClient(config, miniCluster);

其中flinkConfDir为/opt/flink/conf

flink standalone HA集群信息如下：
