Subject Question about jobtracker metrics
Date Mon, 26 Apr 2010 19:13:36 GMT
Hi All,

I was looking at the jobtracker metrics and it seems to be able to give me:
jobs_completed, jobs_submitted, maps_completed, maps_launched, reduces_completed, reduces_launched.

I was wondering what maps launched mean? Is this only the number of maps assigned to the task

I was wondering if it's possible to get the total number of maps that will be generated for
a corresponding job?
