             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: tasktracker
            Reporter: Hemanth Yamijala


MAPREDUCE-467 introduced a framework to collect statistics per node on a fixed set of intervals.
Presently there is support for collecting statistics related to number of task failures and
also health check script failures per hour, day and since start of system. It is felt that
this information can be made available via the tasktracker's metrics system as well.
