Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Affects Versions: 1.0.2

Negative waiting_maps and waiting_reduces count is observed in the mapred metrics. MAPREDUCE-1238 partially fixed this but it appears there is still issues as we are seeing it, but not as bad.

------------------------------------------
I was able to reproduce this using speculative execution and killing the job at the right point when it has speculative tasks running.
