嗨，从我们的spark scala应用程序，我们正在连接到hbase和写作。当我们把jar穿过去时，它就像一个符咒。

<action name="spark-action">
        <spark xmlns="uri:oozie:spark-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <master>yarn-cluster</master>
            <mode>cluster</mode>
            <name>Hbase-Test</name>
              <class>org.sample.ConnectorTest</class>
            <jar>hdfs://nameservice1/app/MyhbaseConnector.jar</jar>
              <spark-opts>--jars ${sparkLib} --files ${files} --driver-class-path ${driverClassPath}
              </spark-opts>
              <arg>testValue</arg>
        </spark>
        <ok to="mail"/>
        <error to="Kill"/>
    </action>

但是，当同样的计划在oozie工作流中以spark动作进行时，我们得到了以下异常。我们还传递了一些Spark的行动选择。
