我尝试通过传递 hadoop 属性以在工作流 xml 文件中引用 tez jar 文件来安排 hive 工作流 xml 文件以在 tez 模式下运行 hive 脚本,如下所示。
<hive xmlns="uri:oozie:hive-action:0.2">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<job-xml>hive-site.xml</job-xml>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>${queueName}</value>
</property>
<property>
<name>tez.lib.uris</name>
<value>${nameNode}/apps/Tez/,${nameNode}/apps/Tez/lib/</value>
</property>
</configuration>
此外,我将 hive-site xml 文件属性 hive.execution.engine 更改为 tez 模式。
<property>
<name>hive.execution.engine</name>
<value>tez</value>
</property>
当我使用 oozie 安排工作流程时。我得到如下错误

任何人都可以说如何纠正这个问题并安排我的工作流 xml 文件并在 tez 模式下运行 hive 脚本。
