Where can I find the webconsole for jobhistory server & what is the command to start the jobhistoryserver. I have started the ResourceManager, NodeManager, NameNode & Datanode.

Answer 1

Go to the sbin in Hadoop root directory.

Command to start jobhistoryserver:

./mr-jobhistory-daemon.sh start historyserver

You can see all the running daemons when you execute jps command.

After this when you try hostname:port/ you can see the job history server.

Default jobhistoryserver port is 19888.
