Hadoop runtime metrics

Hi All,

We have a medium cluster running 70 nodes, using  0.20.2-cdh3u1. We collect run-time metrics thru Ganglia. We found that the certain metrics like  waiting_reduces , tasks_failed_timeout is high and looks the values are getting cumulative. Any thoughts on this will be helpful.

Thanks

You'll need to check with CDH lists.
