Question

我在Cloudera 5.6上并尝试运行简单的Hive脚本工作流程。但我失败了，下面有例外。有什么不对？我将脚本文件和hive-site.xml复制到hdfs文件夹。

这是工作流程定义

<workflow-app name="Add_table_partitions" xmlns="uri:oozie:workflow:0.5">
    <start to="hive-7bc5"/>
    <kill name="Kill">
        <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <action name="hive-7bc5" cred="hcat">
        <hive xmlns="uri:oozie:hive-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
              <job-xml>/user/hive/workflow/hive-site.xml</job-xml>
            <script>/user/hive/workflow/add_partitions.sql</script>
        </hive>
        <ok to="End"/>
        <error to="Kill"/>
    </action>
    <end name="End"/>
</workflow-app>

提前致谢。

Answer 1

看起来版本与MetaStore和HiveLibraries不匹配

试试这个
