Hadoop Datanode从不与所有其他守护进程一起启动

当我启动Ubuntu时，所有的数据节点都会运行，但数据节点不会。我必须删除数据节点才能重新启动。请告诉我更好的解决方案

starting resourcemanager, logging to /usr/local/hadoop/logs/yarn-hduser-resourcemanager-sanjeebpanda-VirtualBox.out
localhost: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-hduser-nodemanager-sanjeebpanda-VirtualBox.out

谁能给我解释一下下面突出显示的部分吗。 hadoop数据节点
