The best way(According to me ) to schedule a Hbase Map_Reduce job is to schedule it as a .java file . It works well and there is no need to write code to change your scan to string , etc. So i am scheduling my jobs like java file till i get any better option .

workflow-app xmlns="uri:oozie:workflow:0.1" name="java-main-wf">
<start to="java-node"/>
<action name="java-node">
    <java>
          <job-tracker></job-tracker>
        <name-node></name-node>
        <configuration>
            <property>
                <name>mapred.job.queue.name</name>
                <value>${queueName}</value>
            </property>
        </configuration>
        <main-class>org.apache.oozie.example.DemoJavaMain</main-class>
        <arg>Hello</arg>
        <arg>Oozie!</arg>
     <arg>This</arg>
        <arg>is</arg>
     <arg>Demo</arg>
        <arg>Oozie!</arg>

    </java>
    <ok to="end"/>
    <error to="fail"/>
</action>
<kill name="fail">
    <message>Java failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
