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.
Regards,
Anis
M.Tech. Student
Take a look at JobInProgress.java. There is one object per job.

Friends,
When Tasktracker exits, then data persist on linux
filesystem. (I am using Hadoop without HDFS)
but when I restart the tasktracker on that node it cleans all data on
it's directory.
Is this normal behavior and what I have to do to persist
that data even
Hi friends,
I am using Hadoop 0.20.2 version.

Thanks for Replying,
I am using shared directory to store the data
