I have a very strong urge to say rtfm
if you a specific question do come back and post.
I use Hadoop 2.2 and I want to run MapReduce web UI. So I visit following url: http://x.x.x.x:50030/jobtracker.jsp
Unable to connect Firefox can't establish a connection to the server at x.x.x.x:50030. Where am I wrong?
I would like to know if you have any examples or tutorials where I can learn hadoop mapReduce on mongodb in java?
To run a job we use the command
$ hadoop jar example.jar inputpath outputpath
If job is so time taken and we want to stop it in middle then which command is used? Or is there any other way to do that?
