Subject Hadoop runtime metrics
Date Tue, 06 Mar 2012 18:54:11 GMT
Hi All,

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