Hi Harsh

Appreciate the response. I was able to configure and implement basic JUnits
within eclipse and get some code running. Still getting familiar with the
new YARN and federation architecture.

I was, however, not able to check the MR jobs submitted within eclipse for
a sample WordCount program on the
http://localhost:8088/<http://localhost:8080/>page. I am starting my
namenode/datanode/resourcemanager/nodemanager/historyserver as instructed
on the wiki page. And then executing JUnit tests from eclipse.

I believe a single MR job will be submitted as a single application in the
new framework, right? The eclipse console shows a successful execution (the
details are pretty neat). However, the webpage shows 'No applications
submitted'. Do I have to tweak with any config properties to get this done?

Please let me know.

Regards,
Prajakta
