OOZIE 状态检查抛出 java.lang.NullPointerException

Question

我是oozie的新手，试图用CDH4.1.1编写oozie工作流程。所以我启动了oozie服务，然后使用以下命令检查状态：

sudo service oozie status

我收到消息：

running

然后我尝试了以下命令来检查状态：

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

我得到了以下异常：

java.lang.NullPointerException
    at java.io.Writer.write(Writer.java:140)
    at org.apache.oozie.client.AuthOozieClient.writeAuthToken(AuthOozieClient.java:182)

    at org.apache.oozie.cli.OozieCLI.main(OozieCLI.java:176)

阅读异常堆栈，我无法找出此异常的原因。请让我知道为什么我收到此异常以及如何解决此问题。

Answer 1

尝试在群集中禁用 env 属性USE_AUTH_TOKEN_CACHE_SYS_PROP。根据您的堆栈跟踪和代码.

通常，群集使用基于 Kerberos 的身份验证进行设置，这是按照此处的步骤设置的。不确定您是否要这样做，但只是想仅供参考。
