1.client模式异常 Yarn application has already ended!
解决:
hadoop的配置文件yarn-site.xml,添加如下内容:
<property>
<name>yarn.nodemanager.pmem-check-enabled</name>
<value>false</value>
</property>
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
注意:
修改完配置文件后需要分发到各个节点,并重启Hadoop
