Question

我正在使用Oozie作为任务管理器的Hadoop集群。我的一个队友犯了一个错误，并在集群上运行了以下oozie工作流程：

<?xml version="1.0" encoding="UTF-8"?>
<!-- A adapter ... -->
<workflow-app xmlns="uri:oozie:workflow:0.5" name="My-Workflow">

            <property>

                <value>${wf:conf('queueName')}</value>
            </property>
        </configuration>
    </global>

    <start to="compute-start"/>

    <fork name="compute-start">

以及子工作流程的示例：

                <value>${wf:conf('queueName')}</value>
            </property>
        </configuration>
    </global>

    <start to="oracle-compute-ci_mr_rem"/>

    <action name="oracle-compute-ci_mr_rem">
        <sub-workflow>
            <app-path>${wf:conf('app.dir')}/oozie/_Oracle-workflow.xml</app-path>
            <propagate-configuration/>

                </property>
                <property>
                    <name>computeSourceName</name>
                    <value>SourceName</value>
                </property>
            </configuration>
        </sub-workflow>
        <ok to="compute-end"/>
        <error to="fail"/>
    </action>

    <join name="compute-end" to="end"/>

    <kill name="fail">
        <message>Job failed, error message: ${wf:errorMessage(wf:lastErrorNode())}</message>
    </kill>

    <end name="end"/>
</workflow-app>

自从此工作流成为逻辑炸弹以来，它就无限地复制自身（及其子工作流）...我想“ fork”操作会将父工作流复制到子工作流中（就像程序过程一样）。

我迅速删除了工作流程文件和目录并运行了命令：

oozie jobs -kill -filter user=my_user

但这并不会停止该过程，作业仍然存在并且正在复制。

需要帮助，有什么主意吗？

Answer 1

重新启动集群。 Oozie作业将不会重新启动。

无法阻止Oozie逻辑炸弹
