The Python rookie of the Hadoop combat--hadoop2.6.0 yarn

Previous article--hadoop2.6.0 cluster deployment, we can see that the Hadoop cluster started after the service situation:

[Email protected] ~]$ jps27888 SecondaryNameNode27688 NameNode28430 Jps28044 ResourceManager31596 jobhistoryserver

If you have already searched for Hadoop, or have heard of MapReduce, there may be more online data: Jobtracker, Tasktracker.

Then you start wondering, well Jobtracker & Tasktracker, is there a problem with the deployment steps?

You'll understand when you're finished with http://www.ibm.com/developerworks/cn/opensource/os-cn-hadoop-yarn/.

No doubt, ResourceManager & NodeManager is the new role in yarn, replacing the Jobtracker & Tasktracker in the old frame.

OK, if you encounter any problems during use, don't suspect that MapReduce is not deployed. ~~~~~~~
