【问题描述】：

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，但出现错误。

我在 ubuntu 18.04 上使用 hadoop 3.2.0、jdk-11。我成功地用namenode和2个datanodes启动了hdfs。当我使用 start-yarn.sh 和以下配置启动纱线（单节点）时会导致错误。

在 etc/hadoop/yarn-site.xml 中

<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>

然后我得到如下错误

【解决方案1】：

我使用 hadoop 3.2.0，JDK-11...Error injecting constructor, java.lang.NoClassDefFoundError: javax/activation/DataSource

Hadoop 仍然需要具有此类的 Java 8
