./sbin/start-yarn.sh
jps
jps上找不到 resourceManager 和 nodeManger的进程， 查询日志发现以下错误信息
resourceManager报错

应该为Java造成的问提
我的Java版本是 jdk10， 貌似自从jdk9以后 java9默认禁用访问许多javax. * API。更换jdk8即可。
还有一种解决方案 https://issues.apache.org/jira/browse/HADOOP-14978，
修改$HADOOP_HOME/etc/hadoop/yarn-env.sh
export YARN_RESOURCEMANAGER_OPTS="--add-moles=ALL-SYSTEM"
export YARN_NODEMANAGER_OPTS="--add-moles=ALL-SYSTEM"追问我的不是这个原因
