,可以通过以下步骤实现:
#!/bin/bash
# 执行Python脚本
python your_python_script.py
# 读取hive表
hive -e "SELECT * FROM your_hive_table;"
<workflow-app xmlns="uri:oozie:workflow:0.5" name="shell-oozie-workflow">
<start to="shell-node"/>
<action name="shell-node">
<shell xmlns="uri:oozie:shell-action:0.3">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<exec>your_shell_script.sh</exec>

</data-in>
</input-events>

</workflow>
</action>
</coordinator-app>
请注意,上述配置文件中的${jobTracker}
、${nameNode}
、${workflowAppUri}
、${start_time}
、${end_time}
、your_python_script.py
、your_hive_table
、your_input_path
等需要根据实际情况进行替换。
以上是在shell oozie操作中读取python脚本中的hive表的步骤。在实际应用中,可以根据具体需求进行调整和优化。
