kerberos 环境的 Oozie Spark 操作失败

Question

我正在运行通过 oozie spark 操作执行 spark 作业。 spark 作业使用 hivecontext 来执行一些要求。集群配置了 kerberos。当我使用 spark-submit 表单控制台提交作业时，运行ning 成功。但是当我运行来自 oozie 的作业时，出现以下错误。

18/03/18 03:34:16 INFO metastore: Trying to connect to metastore with URI thrift://localhost.local:9083
    18/03/18 03:34:16 ERROR TSaslTransport: SASL negotiation failure
    javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

            at org.apache.thrift.transport.TSaslClientTransport.handleSaslStartMessage(TSaslClientTransport.java:94)

workflow.xml

<workflow-app xmlns="uri:oozie:workflow:0.5" name="workflow">
   <start to="analysis" />
   <!-- Bash script to do the spark-submit. The version numbers of these actions are magic. -->
   <action name="Analysis">
      <spark xmlns="uri:oozie:spark-action:0.1">
         <job-tracker>${jobTracker}</job-tracker>
         <name-node>${nameNode}</name-node>
         <master>${master}</master>
         <name>Analysis</name>
         <class>com.demo.analyzer</class>
         <jar>${appLib}</jar>
         <spark-opts>--jars ${sparkLib} --files ${config},${hivesite} --num-executors ${NoOfExecutors} --executor-cores ${ExecutorCores} --executor-memory ${ExecutorMemory} --driver-memory ${driverMemory}</spark-opts>
      </spark>
      <ok to="sendEmail" />
      <error to="fail" />
   </action>
   <action name="sendEmail">
      <email xmlns="uri:oozie:email-action:0.1">
         <to>${emailToAddress}</to>
         <subject>Output of workflow ${wf:id()}</subject>
         <body>Results from line count: ${wf:actionData('shellAction')['NumberOfLines']}</body>
      </email>
      <ok to="end" />
      <error to="end" />
   </action>
   <!-- You wish you'd ever get Oozie errors. -->
   <kill name="fail">
      <message>Bash action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
   </kill>
   <end name="end" />
</workflow-app>

我是否需要在 workflow.xml 中配置与 Kerberos 相关的任何内容？我在这里遗漏了什么吗？

感谢任何帮助。

提前致谢。

Answer 1

在服务器中上传您的密钥表，然后将此密钥表文件和凭据作为您工作流程中 spark-opts 中的参数。让我知道它是否有效。谢谢

<spark-opts>--keytab nagendra.keytab --principal "nagendra@domain.com"
 --jars ${sparkLib} --files ${config},${hivesite} --num-executors ${NoOfExecutors} --executor-cores ${ExecutorCores} --executor-memory
 ${ExecutorMemory} --driver-memory ${driverMemory}</spark-opts>

Answer 2

您需要在 oozie 工作流中为 thrift uri 添加 hcat 凭据。这将启用使用 Kerberos 的 thrift URI 的 Metastore 成功身份验证。

在 oozie 工作流中的凭据标记下方添加。

<credentials>
    <credential name="credhive" type="hcat">
        <property>
            <name>hcat.metastore.uri</name>
            <value>${thrift_uri}</value>
        </property>
        <property>
            <name>hcat.metastore.principal</name>
            <value>${principal}</value>
        </property>
    </credential>
</credentials>

并向 spark 操作提供凭证，如下所示：

<action name="Analysis" cred="credhive">
      <spark xmlns="uri:oozie:spark-action:0.1">
         <job-tracker>${jobTracker}</job-tracker>
         <name-node>${nameNode}</name-node>
         <master>${master}</master>
         <name>Analysis</name>
         <class>com.demo.analyzer</class>
         <jar>${appLib}</jar>
         <spark-opts>--jars ${sparkLib} --files ${config},${hivesite} --num-executors ${NoOfExecutors} --executor-cores ${ExecutorCores} --executor-memory ${ExecutorMemory} --driver-memory ${driverMemory}</spark-opts>
      </spark>
      <ok to="sendEmail" />
      <error to="fail" />
   </action>

thrift_uri和principal可以在hive-site.xml中找到。 thrift_uri 将设置在 hive-site.xml 属性:

<property>
    <name>hive.metastore.uris</name>
    <value>thrift://xxxxxx:9083</value>
  </property>

此外，主体将设置在 hive-site.xml 属性:

 <property>
    <name>hive.metastore.kerberos.principal</name>
    <value>hive/_HOST@domain.COM</value>
  </property>
