我已在本地成功测试了我的Flink wordcount应用，但在群集上运行我遇到了以下错误
Exception in thread "main" org.apache.flink.client.program.ProgramInvocationException: Cannot establish connection to JobManager: hduser@192.168.101.10: Name or service not known
我的flink群集在VirtualBox上创建，包括3个节点，一个Jobmanager和两个TaskManager，而JobManager在地址192.168.101.10和端口6123上运行。
所以在java代码中我使用以下命令来创建StreamExecutionEnvironment对象
final StreamExecutionEnvironment env = StreamExecutionEnvironment.createRemoteEnvironment("hduser@192.168.101.10", 6123);
hduser是用户拥有的JobManager。
我使用命令
在我的主机操作系统（运行VirtualBox）中运行jar文件java -cp flink-quickstart-java.jar WordCountStreamingCluster --port 9000
更新 如果在以下行中未使用用户名作为群集地址：
final StreamExecutionEnvironment env = StreamExecutionEnvironment.createRemoteEnvironment("192.168.101.10", 6123);
我遇到了以下错误：

我该如何解决这个问题？
