client.RMProxy: Connecting to ResourceManager at /127.0.0.1:8032

问题

I want to run map reduce job with:

bin/hadoop jar wc.jar WordCount /user/hadoop/input /user/hadoop/output

As see in picture, The execution gets stuck in connecting to the resource manager and I don't have any error. Using jps, Resource Manager is running but also localhost:8032 can not works on the browser. yarn-site.xml:

<configuration>
    <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
    </property>
    <property>
    <name>yarn.resourcemanager.address</name>
    <value>127.0.0.1:8032</value>
    </property>
    <property>
    <name>yarn.resourcemanager.scheduler.address</name>
    <value>127.0.0.1:8030</value>
    </property>
    <property>
    <name>yarn.resourcemanager.resource-tracker.address</name>
    <value>127.0.0.1:8031</value>
    </property>
</configuration>

Please help me how to run jar properly.
