Subject task tracker statistics
Date Sat, 11 Dec 2010 23:17:39 GMT
Hi I am just starting to learn about mapreduce. Could any one give
inputs how to get the statistics for the task trackers in the cluster
. Like if run jobs on the cluster for whole day, i want to get a file
on the master node with aggregate statistics for whole day like

tasktracker id    total number of tasks assigned     total number of
tasks failed

I see from some of the default reports available these are recorded
only during the job is ran, but i want those values to be persistent
after the job execution is done too.
