You can use RunningJob handle to query map/reduce progress.
See api @
http://hadoop.apache.org/core/docs/r0.20.0/api/org/apache/hadoop/mapred/RunningJob.html

Look at JobClient -- There are some useful methods there.
For example, displayTasks and monitorAndPrintJob might provide most of the

Hi,
I am looking for the following:
for each task: % completed for both map n reduce, exceptions (if
encountered).
for each job: % completed, status (RUNNING,FAILED,PAUSED etc).
i would wanna write a program so that i can programatically access the above
information at any point of time.
Thanks,

Could you let us know what information are you looking to extract from
