Why would you want to read the status and write some other application
when Hadoop provides cluster monitoring webapps at ports 50030, 50060
and 50070 ?

Currently I was trying to read the log files generated by hadoop so
that I
could show the status of map/reduce jobs in user interfaces
(consider that UI is a separate application )
I was looking at JobTracker APIs and was trying use following APIs
1. jobtracker.getAllJobs() which returns array of jobstatus objects
2. Then for each jobStatus we can call
mapProgress() , isJobCompleted() methods
The problem is how do I link existing jobTracker ( which is already
running
) with my code ? i am trying to built something like " hadoop UI ."
should I use jobClient APIs ? Also is this a proper approach ?
thanks in advance . N mark.
