Todd Lipcon commented on MAPREDUCE-6065:
----------------------------------------
Ah, I see now that you're right, Binglin. My trunk terasort generated the same
warnings in its logs:
{code}
...
2014-09-02 17:42:28,437 INFO [main] org.apache.hadoop.mapred.MapTask: Map
output collector class = org.apache.hadoop.mapred.MapTask$MapOutputBuffer
2014-09-02 17:42:42,238 WARN [main] org.apache.hadoop.util.Progress: Illegal
progress value found, progress is larger than 1. Progress will be changed to 1
2014-09-02 17:42:42,238 WARN [main] org.apache.hadoop.util.Progress: Illegal
progress value found, progress is larger than 1. Progress will be changed to 1
2014-09-02 17:42:42,241 INFO [main] org.apache.hadoop.mapred.MapTask: Starting
flush of map output
...
{code}
I'll close this one as invalid.

> In running terasort tests, I see a few warnings like this:

> progress value found, progress is larger than 1. Progress will be changed to 1
> It sounds like we're improperly calculating task progress somewhere. We
