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

Question

我正在尝试通过URL执行Oozie作业： https : //www.safaribooksonline.com/library/view/apache-oozie/9781449369910/ch05.html

在执行oozie job -run -config target/example/job.properties

出现错误为：

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？

Answer 1

它无法从Oozie客户端（命令行）连接到Oozie服务器。 查找Oozie服务器URL，然后执行以下操作之一：

• 将Oozie服务器设置（导出）为环境变量export OOZIE_URL=http://hostname:11000/oozie
• 在-oozie命令中使用-oozie参数。 oozie job -oozie http://hostname:11000/oozie -run -config target/example/job.properties
