Question

我编写了一个Sqoop导入脚本，用于将数据从teradata导入到hive。当我从命令行运行它时工作正常，但当我把它放在shell脚本中并尝试通过oozie工作流程执行时，我得到以下错误

当您可以/应该使用Sqoop操作时，看起来您正在使用shell操作。运行Sqoop作业时需要包含几个罐子。其中大多数都包含在oozie sharelib中。这是一个示例工作流程：

<workflow-app name="sqoop-to-hive" xmlns="uri:oozie:workflow:0.4">
    <start to="sqoop2hive"/>
    <action name="sqoop2hive">
        <sqoop xmlns="uri:oozie:sqoop-action:0.2">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <command>import --connect jdbc:mysql://mysql.example.com/sqoop --username sqoop --password sqoop --table test --hive-import --hive-table test</command>
            <archive>/tmp/mysql-connector-java-5.1.31-bin.jar#mysql-connector-java-5.1.31-bin.jar</archive>
            <file>/tmp/hive-site.xml#hive-site.xml</file>
        </sqoop>
        <ok to="end"/>
        <error to="kill"/>
    </action>
    <kill name="kill">
        <message>Action failed</message>
    </kill>
    <end name="end"/>
</workflow-app>

我建议关注如何使用oozie和sqoop的guide。
