i recently made the switch from hadoop 0.20.x to hadoop 2.3.0 (yes, big
leap). i was wondering if there is a way to view my jobs now via a web UI?
i used to be able to do this by accessing the following URL
http://hadoop-cluster:50030/jobtracker.jsp
however, there is no more job tracker
Yes. JobTracker and TaskTracker are gone from all the 2.x release lines.
MapReduce is an application on top of YARN. That is per job - launches, starts
and finishes after it is done with its work. Once it is done, you can go look
at it in the MapReduce specific JobHistoryServer.

all i see on the UI is: No data available in table.
any ideas?

ok, the reason why hadoop jobs were not showing up was because i did not
enable mapreduce to be run as a yarn application.
