Hadoop作业和任务跟踪器不工作 [英] Hadoop Job and Task Tracker not working

问题描述

当我开始hadoop作业跟踪器和任务跟踪器不工作。

when i start hadoop job tracker and task tracker not working.

我使用两台电脑。 master- furkanb @ master 192.168.2.135和slave-detay @ slave
192.168.2.250。

I'm working with two computers. master- furkanb@master 192.168.2.135 and slave- detay@slave 192.168.2.250.

xml并在两台计算机上托管相同的文件。

xml and hosts files the same on 2 computers.

我已写入控制台jps。

I have written to the console jps.

15568 Jps
12126 SecondaryNameNode
11812 NameNode
11934 DataNode
12314 ResourceManager

主机：

/ etc / hadoop / masters furkanb @ master

/etc/hadoop/masters furkanb@master

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

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

奴隶机器：

/ etc / hadoop / slaves localhost

/etc/hadoop/slaves localhost

当我在控制台上写start-all.sh：

When i write start-all.sh on console :

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

我可以达到localhost：50070和master：50070。但我不能到达localhost：50030或master：50030

I can reach localhost:50070 and master:50070. But i can't reach localhost:50030 or master:50030

推荐答案

您使用Yarn不是经典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

You are using Yarn not classic mapreduce. You cannot find Jobtracker here. For checking the status of running applications you need to use resource manager's http port. ie 8088

查看以下网址
localhost：8088

Check out the following URL localhost:8088
