我正在尝试使用 oozie scheduler 运行 mahout 命令 - sequence2sparse，但它给出了一些错误。我尝试使用 oozie - shell 标签运行 mahout 命令，但没有任何效果。

以下是 oozie 工作流程 -

 <action name="mahoutSeq2Sparse">
      <shell xmlns="uri:oozie:shell-action:0.1">
        <job-tracker>${jobTracker}</job-tracker>
        <name-node>${nameNode}</name-node>
        <configuration>
            <property>
              <name>mapred.job.queue.name</name>
              <value>${queueName}</value>
            </property>
        </configuration>
        <exec>mahout seq2sparse</exec>
         <argument>-i</argument>
         <argument>${nameNode}/tmp/Clustering/seqOutput</argument>
         <argument>-o</argument>
         <argument>${nameNode}/tmp/Clustering/seqToSparse</argument>
         <argument>-ow</argument>
         <argument>-nv</argument>
         <argument>-x</argument>
         <argument>100</argument>
         <argument>-n</argument>
         <argument>2</argument>
         <argument>-wt</argument>
         <argument>tf</argument>
         <capture-output/>
     </shell>
 <ok to="brandCanopyInitialCluster" />
    <error to="fail" />
</action>

我还尝试创建一个 shell 脚本并在 oozie 中运行它

 <action name="mahoutSeq2Sparse">
       <shell xmlns="uri:oozie:shell-action:0.1">
        <job-tracker>${jobTracker}</job-tracker>
        <name-node>${nameNode}</name-node>
        <configuration>
            <property>
              <name>mapred.job.queue.name</name>
              <value>${queueName}</value>
            </property>
        </configuration>
        <exec>${EXEC}</exec>
        <file>${EXEC}#${EXEC}</file>
     </shell>

    <ok to="brandCanopyInitialCluster" />
    <error to="fail" />
</action>

与 job.properties 作为

nameNode=hdfs://abc02:8020
jobTracker=http://abc02:8050/
 clusteringJobInput=hdfs://abc02:8020/tmp/Activity/000000_0
queueName=default
oozie.wf.application.path=hdfs://abc02:8020/tmp/workflow/
oozie.use.system.libpath=true
EXEC=generatingBrandSparseFile.sh

和 generateBrandSparseFile.sh 是

    export INPUT_PATH="hdfs://abc02:8020/tmp/Clustering/seqOutput"
export OUTPUT_PATH="hdfs://abc02:8020/tmp/Clustering/seqToSparse"


sudo -u hdfs hadoop fs -chmod -R 777     "hdfs://abc02:8020/tmp/Clustering/seqOutput"

mahout seq2sparse -i ${INPUT_PATH} -o ${OUTPUT_PATH} -ow -nv -x 100  -n 2 -wt tf
sudo -u hdfs hadoop fs -chmod -R 777 ${OUTPUT_PATH}

但没有一个选项有效。后一个的错误是 -

SLF4J：有关说明，请参见http://www.slf4j.org/codes.html#multiple_bindings。SLF4J：实际绑定的类型为 [org.slf4j.impl.Log4jLoggerFactory] ​​sudo：不存在 tty，也没有指定 askpass 程序 15/06/05 12:23:59 WARN driver.MahoutDriver：在类路径上找不到 seq2sparse.props，将仅使用命令行参数 15/06/05 12:24:01 INFO vectorizer.SparseVectorsFromSequenceFiles：最大 n-gram 大小为：1

对于sudo: no tty present这个错误，我已经注释掉 /etc/sudoers - Defaults !requiretty

Mahout 安装在安装 oozie 服务器的节点上。

以下 oozie 工作流程也无效-

<workflow-app xmlns="uri:oozie:workflow:0.4" name="map-reduce-wf">
<action name="mahoutSeq2Sparse">
       <ssh>
        <host>rootUserName@abc05.ad.abc.com<host>
        <command>mahout seq2sparse</command>
        <args>-i</arg>
        <args>${nameNode}/tmp/Clustering/seqOutput</arg>
        <args>-o</arg>
        <args>${nameNode}/tmp/Clustering/seqToSparse</arg>
        <args>-ow</args>
        <args>-nv</args>
        <args>-x</args>
        <args>100</args>
        <args>-n</args>
        <args>2</args>
        <args>-wt</args>
        <args>tf</args>
         <capture-output/>
      </ssh>

    <ok to="brandCanopyInitialCluster" />
    <error to="fail" />
</action>

错误-Error: E0701 : E0701: XML schema error, cvc-complex-type.2.4.a: Invalid content was found starting with element 'ssh'. One of '{"uri:oozie:workflow:0.4":map-reduce, "uri:oozie:workflow:0.4":pig, "uri:oozie:workflow:0.4":sub-workflow, "uri:oozie:workflow:0.4":fs, "uri:oozie:workflow:0.4":java, WC[##other:"uri:oozie:workflow:0.4"]}' is expected.

在所有节点上安装 mahout 会有帮助吗？-（oozie 可以在任何节点上运行脚本）。有没有办法让 mahout 在 hadoop 集群上可用？

也欢迎任何其他解决方案。

提前致谢。

编辑：我稍微改变了方法，现在我直接调用 seq2sparse 类。工作流程是 -

 <action name="mahoutSeq2Sparse">
    <java>
      <job-tracker>${jobTracker}</job-tracker>
      <name-node>${nameNode}</name-node>

       <configuration>
            <property>
                <name>mapred.job.queue.name</name>
                <value>${queueName}</value>
            </property>

        </configuration>
            <main-class>org.apache.mahout.vectorizer.SparseVectorsFromSequenceFiles</main-class>
            <arg>-i</arg>
         <arg>${nameNode}/tmp/OozieData/Clustering/seqOutput</arg>
         <arg>-o</arg>
         <arg>${nameNode}/tmp/OozieData/Clustering/seqToSparse</arg>
         <arg>-ow</arg>
         <arg>-nv</arg>
         <arg>-x</arg>
         <arg>100</arg>
         <arg>-n</arg>
         <arg>2</arg>
         <arg>-wt</arg>
         <arg>tf</arg>

    </java>
    <ok to="CanopyInitialCluster"/>
    <error to="fail"/>
</action>

作业仍然没有运行，错误是

Oozie 上的这些错误非常令人沮丧。根据我的经验，它们中的大多数是由 xml 中的拼写错误或参数顺序产生的。

在上一个工作流程中，您没有关闭主机标签：

<host>rootUserName@abc05.ad.abc.com<host>

应该

<host>rootUserName@abc05.ad.abc.com</host>

对于 shell 错误，首先我建议使用 0.2 版（在此处定义：https ://oozie.apache.org/docs/4.0.0/DG_ShellActionExtension.html#AE.A_Appendix_A_Shell_XML-Schema ）并删除所有参数和一切对开始行动没有用处（不关心结果）。

您需要使用：

<shell xmlns="uri:oozie:shell-action:0.2">
