**与hadoop集群的配置xml对应**  
core-site.xml

<property>
            <name>fs.defaultFS</name>
            <value>hdfs://hadoop-master:9000</value>
        </property>

hdfs-site.xml

<property> 
            <name>dfs.namenode.secondary.http-address</name> 
            <value>hadoop-master:9001</value> 
        </property>

如果找不到Map/Reduce Location需要手动打开
