级联驱动的自托管版本服务器错误

Question

我在Cloudera-5 (CDH-5) VM中使用驱动自托管版本。

我能够成功地安装驱动服务器，并且能够在URL localhost.localdomain:8080中打开服务器。

我在文件cascading-service.properties中提供了以下值

cascading.management.document.service.apikey=API_KEY from Driven Server
cascading.management.service.jar=/usr/lib/cascading-2.5.5/driven-plugin-1.0.1-eap-68-io.jar
cascading.management.document.service.hosts=localhost.localdomain

但我在执行级联作业时遇到以下错误，作业不会显示在Driven Server中。但级联作业已成功完成。

我尝试给出值localhost、localhost.localdomain、127.0.0.1以及VM的IP，但每次都会遇到相同的错误。

我是不是漏掉了什么？请协助解决此问题。

你还没有尝试过这个：

cascading.management.document.service.hosts=http://localhost:8080

应该行得通。
