Todd Lipcon created MAPREDUCE-6068:
--------------------------------------
Summary: Illegal progress value warnings in map tasks
Key: MAPREDUCE-6068
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6068
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2, task
Affects Versions: 3.0.0

When running a terasort on latest trunk, I see the following in my task 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}
We should eliminate these warnings.
