我是Hadoop和YARN的新手。 启动 hdfs 后，我使用包中提供的 start-yarn.sh 启动 YARN 并得到错误。
我在ubuntu 18.04上使用hadoop 3.2.0，jdk-11。 我成功地用 namenode 和 2 个数据节点启动了 hdfs。 当我使用以下配置启动纱线(单节点(时 start-yarn.sh 会导致错误。
In etc/hadoop/yarn-site.xml
<configuration>
<property>
<name>yarn.acl.enable</name>
<value>0</value>
</property>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>10.0.0.87</value>
</property>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>
然后我得到了如下错误

寻求您的帮助。非常感谢
我使用hadoop 3.2.0，JDK-11...

Hadoop仍然需要Java 8，它有这个类
