Cloudera 5 - oozie PoolableConnectionFactory

Question

我已经安装了cloudera 5管理器，现在我正在尝试使用此示例https://github.com/cloudera/cdh-twitter-example。

启动数据管道，日志显示：

SERVER [xxxx]服务加载期间的运行时异常。检查“oozie.services”或“oozie.services.ext”

列表

SERVER [xxxx] E0103：无法加载服务类，无法创建PoolableConnectionFactory（通信链接失败） org.apache.oozie.service.ServiceException：E0103：无法加载服务类，无法创建PoolableConnectionFactory（通信链接失败

引起：org.apache.openjpa.persistence.PersistenceException：无法创建PoolableConnectionFactory（通信链接失败

任何想法？我看不到错误..

提前致谢。

每次重新启动CDH5时，都会在/ run / cloudera-scm-agent / process中创建一个文件夹，这是正确的吗？

/run/cloudera-scm-agent/process/459-oozie-OOZIE_SERVER/oozie-site.xml
