Hadoop作业和任务跟踪器无法正常工作

Question

当我启动hadoop作业跟踪器和任务跟踪器不工作时。

我正在使用两台电脑。 master-furkanb @ master 192.168.2.135和slave-detay @ slave 192.168.2.250。

xml并在2台计算机上托管相同的文件。

我已写入控制台jps。

当我在控制台上写start-all.sh时：

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

我可以访问localhost：50070和master：50070。但我无法访问localhost：50030或master：50030

你正在使用Yarn而不是经典的mapreduce。你在这里找不到Jobtracker。要检查正在运行的应用程序的状态，您需要使用资源管理器的http端口。即8088
