OOZIE 状态检查抛出 java.lang.NullPointerException

OOZIE status check throws java.lang.NullPointerException

我是 oozie 的新手,正在尝试在 CDH4.1.1 中编写一个 oozie 工作流程。所以我启动了 oozie 服务,然后我使用这个命令检查了状态:

sudo service oozie status

我收到消息:

running

然后我尝试了这个命令来检查状态:

oozie admin --oozie http://localhost:11000/oozie status

我得到以下异常:

java.lang.NullPointerException

读取异常堆栈,我无法弄清楚这个异常的原因。请告诉我为什么会出现此异常以及如何解决此问题。

尝试禁用集群中的环境 属性 USE_AUTH_TOKEN_CACHE_SYS_PROP。根据您的堆栈跟踪和 code

通常集群是使用基于 Kerberos 的身份验证设置的,这是按照 here 的步骤设置的。不确定您是否想这样做,但只是想将其作为仅供参考。
