Hadoop 作业和任务跟踪器不工作

Question

当我启动 hadoop job tracker 和 task tracker 时不工作。

我正在使用两台计算机。 master-furkanb@master 192.168.2.135 和 slave-detay@slave192.168.2.250。

xml 和 hosts 文件在 2 台计算机上相同。

我已经写到控制台jps了。

主机:

/etc/hadoop/masters furkanb@master

/etc/hadoop/slaves furkanb@master detay@slave

从机:

/etc/hadoop/slaves localhost

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

我可以到达 localhost:50070 和 master:50070。但我无法到达 localhost:50030 或 master:50030

您使用的是 Yarn 而不是经典的 mapreduce。您在这里找不到 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
