I believe the closest you can get at this time is using the JobClient class: here

This will allow you to see running jobs, or walk all jobs.

Check out the <hadoopdir>/conf/mapred-site.xml configuration file.

In this file, you should find a <property> that has a <name> of mapred.job.tracker:

<property>
    <name>mapred.job.tracker</name>
    <value>node5:12345</value>
<property>

This tells you what node it is running on and what port it is running on.

If you are looking for any specific information, please elaborate in your original question.
