jobtracker和tasktracker无法打开 [英] jobtracker and tasktracker not opening

问题描述

我已经成功安装了ubuntu 12.04和hadoop 2.3.0。进入jps命令后，我发现输出如下所示：
$
$ b

b $ b

  4135 jps 
 2582 SeconadaryNameNode 
 3143 NodeManager 
 2394 Namenode 
 2391 Datanode 
 3021 ResourceManager 
  

为什么它没有显示jobtracker和tasktracker。
i尝试了start-mapred.sh，但它显示命令没有找到（我搜索了hadoop目录没有找到这样的文件，所以我认为新版本，即2.0.3已弃用它，必须有其他方式启动jobtracker和$ $
$ b

localhost：50070完全正常
但localhost：50030和localhost：50060显示无法连接。

所以任何人都可以帮我解决这个问题吗？ 你已经用YARN安装了Hadoop 2.x 。 JobTracker和Tasktracker现在被NodeManager，ResourceManager和Application Master取代。有关YARN（MRv2）的更多信息。

i have successfully installed ubuntu 12.04 and hadoop 2.3.0.

after entering the jps command i find the output as below

4135 jps
2582 SeconadaryNameNode
3143 NodeManager
2394 Namenode
2391 Datanode
3021 ResourceManager

why it is not showing the jobtracker and tasktracker. i tried start-mapred.sh but it shows command not found.(i searched the hadoop directory no such file found so i think the newer version i.e 2.0.3 has deprecated it and must be having some other way of starting jobtracker and tasktracker)

localhost:50070 working absolutely fine but localhost:50030 and localhost:50060 shows unable to connect.

so anybody can help me out in this?

解决方案

You have installed the Hadoop 2.x with YARN. The Jobtracker and Tasktracker is replaced now with NodeManager,ResourceManager and Application Master. More Information about YARN (MRv2).
