我试图通过它的web服务api（oozie4.1.0-cdh5.15.2）执行一个oozie作业。以前，这个作业是通过oozie命令行api成功执行的，大多数参数都作为命令参数提供。
workflow.xml当前在hdfs上，因此我只是尝试按文档中指定的格式以xml形式发送作业属性：

POST /oozie/v1/jobs
Content-Type: application/xml;charset=UTF-8
.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property>
        <name>oozie.use.system.libpath</name>
        <value>true</value>
    </property>
    <property>
        <name>oozie.credentials.skip</name>
        <value>true</value>
    </property>
    <property>
        <name>oozie.wf.application.path</name>
        <value>hdfs://myownhdfs.com:8020/path/to/oozie/workflow/workflow.xml</value>
    </property>
    <property>
        <name>jobTracker</name>
        <value>myownhdfs.com:8032</value>

    <property>
        <name>nameNode</name>
        <value>hdfs://myownhdfs.com:8020</value>

    <property>
        <name>customScripts</name>
        <value>/nfs/path/to/scripts</value>
    </property>
</configuration>

我的工作流.xml

<?xml version="1.0" encoding="UTF-8"?>
<workflow-app
        xmlns="uri:oozie:workflow:0.5"
        name="wf-check">

            <capture-output />
        </python>
        <ok to="end" />
        <error to="fail" />
    </action>
    <kill name="fail">
        <message>Python failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end" />
</workflow-app>

但是我只收到400个错误的请求：客户端发送的请求语法不正确。。
有人知道我会做错什么吗？
