i can run hadoop commands, such as: hdfs dfs -ls , hdfs dfs -put...., can visit: http://localhost:50070/dfshealth.html#tab-datanode

but why exception happened?

make sure have following on yarn-site.xml

<property>     <name>yarn.resourcemanager.hostname</name>     <value>0.0.0.0</value>   </property>
