我正在尝试使用 Oozie 在 Shell 脚本中运行 Sqoop 作业。请注意,我在本地机器(具有 12G RAM 的 vm)中使用 cdh5,并使用 HUE 来构建工作流程。
我在 shell 脚本中创建了一个 Sqoop 作业,该作业将数据从 Mysql 提取到 HDFS。我使用 Oozie 运行它:
sqoop job --create testmetastore --meta-connect jdbc:hsqldb:hsql://localhost:16000/sqoop -- import --connect jdbc:mysql://localhost:3306/retail_db --table EMPLOYEE --username root --password cloudera --target-dir hdfs://localhost:8020/user/cloudera/EMPLOYEES -m 1
Job 已创建(我可以在执行 list cmd 时找到它,见下文):
sqoop job --list --meta-connect jdbc:hsqldb:hsql://localhost:16000/sqoop
我什至从我的终端执行了这项工作并且它可以工作(见下面的 cmd):
sqoop job --meta-connect jdbc:hsqldb:hsql://localhost:16000/sqoop --exec testmetastore
我删除了最后一个导入的文件夹,并尝试再次执行该作业,但这次是在 Oozie 中。它给出了一个错误(见下文):
18/12/23 10:47:06 INFO mapreduce.ImportJobBase: counters are unavailable. To get this information,

这是 sqoop-site.xml:

这是workflow.xml:

<start to="shell-7268"/>
<kill name="Kill">

</kill>
<action name="shell-7268">
<shell xmlns="uri:oozie:shell-action:0.1">

<name-node>${nameNode}</name-node>
<exec>/user/cloudera/sqpexec.sh</exec>
<file>/user/cloudera/sqpexec.sh#sqpexec.sh</file>
<file>/user/cloudera/sqoop-site.xml#sqoop-site.xml</file>
<capture-output/>
</shell>
<ok to="End"/>
<error to="Kill"/>
</action>
<end name="End"/>
这是 HUE 的视图:HUE 中的工作流程
我试图在 Oozie 的 shell 脚本中运行 sqoop 作业的原因是,我想创建一个 sqoop 作业来记住最后导入的值,以便它可以增加表,然后使用 Oozie 对其进行调度。所以这只是第一步测试!
你能帮忙吗?谢谢,
