Question

我正在尝试使用Oozie在Shell脚本中运行Sqoop作业。请注意，我在本地计算机（具有12G RAM的vm）中使用cdh5，并使用HUE来构建工作流程。

我创建了一个Sqoop作业，该作业在Shell脚本中从Mysql提取数据到HDFS。然后使用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

工作已创建（我在执行cmd列表时可以找到它，请参见下面）：

sqoop job --list --meta-connect jdbc:hsqldb:hsql://localhost:16000/sqoop

sqoop job --list

我什至在终端上执行了该作业，并且该作业有效（请参见下面的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，并试图再次重新执行作业，但这一次是在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, 
18/12/23 10:47:06 INFO mapreduce.ImportJobBase: you will need to enable the completed job store on

这是sqoop-site.xml：

          <property>
    <name>sqoop.metastore.client.enable.autoconnect</name>
    <value>false</value>
    <description>If true, Sqoop will connect to a local metastore
      for job management when no other metastore arguments are
      provided.
    </description>
  </property>

  <property>
    <name>sqoop.metastore.client.autoconnect.url</name>
    <value>jdbc:hsqldb:hsql://localhost:16000</value>
    <description>The connect string to use when connecting to a
      job-management metastore. If unspecified, uses ~/.sqoop/.
      You can specify a different path here.

  </property>
  <property>
    <name>sqoop.metastore.client.autoconnect.username</name>

    </description>
  </property>

  <property>
    <name>sqoop.metastore.server.location</name>
    <value>/tmp/sqoop-metastore/shared.db</value>

    If this is not set, it will be placed in ~/.sqoop/.
    </description>
  </property>

  <property>
    <name>sqoop.metastore.server.port</name>
    <value>16000</value>
    <description>Port that this metastore should listen on.
    </description>
  </property>

这是工作流程.xml：

<workflow-app name="MyWorkflow" xmlns="uri:oozie:workflow:0.5">
<start to="shell-7268"/>
<kill name="Kill">
    <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<action name="shell-7268">
    <shell xmlns="uri:oozie:shell-action:0.1">
        <job-tracker>${jobTracker}</job-tracker>
        <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"/>

我之所以尝试在Oozie的shell脚本中运行一个sqoop作业，是因为我想创建一个sqoop作业来重新导入最后导入的值，以便它可以递增表，然后使用Oozie对其进行调度。因此，这只是第一步测试！

可以帮忙吗？谢谢，
