我想制作一个oozie工作流程,成功的最后一步将是" Archive"结果。
shell中的命令是
hadoop archive -archiveName=XXX.har -p /some/random/parent directorToArhive pathToArchiveDestination
我试过以下
<workflow-app name="HARD_CODED_ARCHIVE_TEST" xmlns="uri:oozie:workflow:0.4">
<start to="archive"/>
<action name="archive">
<archive archiveName="xxx.har" src="/root/src/dir" dest="/path/to/desired/archive/location"/>
<ok to="end"/>
<error to="kill"/>
</action>
<kill name="kill">
<message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
我得到的错误类似于以下内容:
WARNING: Exception in Runloop of thread: main with message: E0701: XML schema error, cvc-complex-type.2.4.a: Invalid content was found starting with element 'archive'. One of '{"uri:oozie:workflow:0.4":map-reduce, "uri:oozie:workflow:0.4":pig, "uri:oozie:workflow:0.4":sub-workflow, "uri:oozie:workflow:0.4":fs, "uri:oozie:workflow:0.4":java, WC[##other:"uri:oozie:workflow:0.4"]}' is expected.
所以很明显我无法做到这一点。因为oozie工作流架构不支持&#34; archive&#34;行动。
我真的不想通过cron运行它,因为我想在工作流成功完成后立即存档我该怎么做。
答案 0 :(得分:3)
试试这个:
<action name="archive">
<java>
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<main-class>org.apache.hadoop.tools.HadoopArchives</main-class>
<arg>-archiveName</arg>
<arg>${YourArchiveName}.har</arg>
<arg>-p</arg>
<arg>${FilesParentDirectory}</arg>
<arg>${SrcDirectory}</arg>
<arg>${DestDirectory}</arg>
</java>
<ok to="end"/>
<error to="error"/>
</action>
您需要的只是工作流程中的hadoop-archives.jar文件。也不要忘记将jar放在工作流目录中,你应该好好去。希望有所帮助!
