Shivam,
Visit JobTrackerHost/conf to see the taskScheduler config that's in effect on the runtime.
Visit JobTrackerHost/scheduler to see a scheduler web UI if its put one up (default does not provide any, others may).
May I ask why you're looking to confirm? Is something not working the way you expect it to?

If you are really worried you could kill -QUIT the JT process and look
in the stack traces.

Is there any other way by which we can check that other scheduler is
actually running and not the default one, rather than checking
mapred-site.xml file

Hi,
Check the mapreduce.jobtracker.taskscheduler property in the
mapred-site.xml, if it's not set then check what it defaults to.

Depending on the version of Hadoop you are using, you can goto
http://<jthost>:50030/scheduler to check.
This will work from hadoop-0.20.203 onwards.
