Where JobTracker stores Task'sinformation
Hi Friends,
I want to know, where JobTracker stores Task's Information,
i.e. which task is being executed on which tasktracker, and how
JobTracker stores this information.
If anyone know this please let me know it.

From where Jobtracker takes information regrading which map &
reduce task fails.
and where it reschedules these map & reduce task (i.e. which
code it executes to reschedule map & reduce task)

Take a look at JobInProgress.java. There is one object per job.
