Hadoop OOZIE:发生连接异常[java.net.ConnectException连接被拒绝（连接被拒绝）]

我正试图在他的帮助下执行Oozie的工作 网址：

执行时

oozie作业-run-config目标/example/job.properties

将错误获取为：

Connection exception has occurred [ java.net.ConnectException Connection refused (Connection refused) ]. Trying after 1 sec. Retry count = 1
Connection exception has occurred [ java.net.ConnectException Connection refused (Connection refused) ]. Trying after 2 sec. Retry count = 2
Connection exception has occurred [ java.net.ConnectException Connection refused (Connection refused) ]. Trying after 4 sec. Retry count = 3
Connection exception has occurred [ java.net.ConnectException Connection refused (Connection refused) ]. Trying after 8 sec. Retry count = 4
Error: IO_ERROR : java.io.IOException: Error while connecting Oozie server. No of retries = 4. Exception = Connection refused (Connection refused)

任何想法；为什么连接被拒绝

它无法从Oozie客户端（命令行）连接到Oozie服务器。找到Oozie服务器url并执行以下操作之一：

• 将Oozie服务器设置为（导出）环境变量

  export Oozie\u URL=http://hostname:11000/oozie

• 在oozie命令中使用

  -oozie

  参数<代码>oozie作业-ooziehttp://hostname:11000/oozie -运行-config target/example/job.properties
