Hadoop Streaming Job无法在OOzie中运行

我正在尝试编写一个简单的 Map ，只有hadoop流式传输作业从hdfs读取数据并将其推送到vertica .

我编写了一个shell脚本，如下所示

./vsql -c "copy $TABLE from stdin delimiter E'\t' direct null '\\N';" -U $DBUSER -w $DBPWD -h $DBHOST -p $DBPORT

我创建了oozie工作流程：

<action name="loadToVertica">
        <map-reduce>
                            <job-tracker>${jobTracker}</job-tracker>
                            <name-node>${nameNode}</name-node>
                            <prepare>
                                    <delete path="${nameNode}/user/$USER/output/${exportDataDate}"/>
                            </prepare>
                            <streaming>
                                    <mapper>shell export.sh</mapper>
                            </streaming>
                            <configuration>
                                    <property>

                                            <value>${wfsBasePath}/libs</value>
                                    </property>
                                    <property>
                                            <name>mapred.input.dir</name>
                                            <value>${nameNode}/user/$USER$/{exportDataDate}</value>
                                    </property>
                                    <property>
                                            <name>mapred.output.dir</name>
                                            <value>${nameNode}/user/$USER/output/${exportDataDate}</value>
                                    </property>
                                    <property>
                                            <name>mapred.reduce.tasks</name>
                                            <value>0</value>
                                    </property>
                            </configuration>
                            <file>${wfsBasePath}/libs/${STREAMING_JAR_PATH}#${STREAMING_JAR_PATH}</file>
                            <file>${wfsBasePath}/libs/oozie-sharelib-streaming-4.2.0.2.5.3.0-37.jar#oozie-sharelib-streaming-4.2.0.2.5.3.0-37.jar</file>

                    </map-reduce>
            <ok to="end"/>
           <error to="end"/>
        </action>

当我运行它时，作业状态为Failed / Killed，没有任何错误消息 .
