我正在尝试在以下工具的帮助下执行 Oozie 作业 网址:https://www.safaribooksonline.com/library/view/apache-oozie/9781449369910/ch05.html
执行时
oozie job -run -config target/example/job.properties
获取错误为:
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？
最佳答案
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(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
