Ravi Gummadi commented on MAPREDUCE-1160:
-----------------------------------------

Checked JobTracker, JobInProgress and TaskInProgress. I don't see any other similar cases
there.

> There are two log statements being logged at an INFO level that are unnecessarily filling
up JT logs. This is making it difficult to debug issues on large cluster systems.
> The two statements identified are the following:
> INFO org.apache.hadoop.mapred.JobInProgress: No reduces to schedule for <jobid>
> and
> INFO org.apache.hadoop.mapred.ResourceEstimator: completedMapsUpdates:22  completedMapsInputSize:656
 completedMapsOutputSize:6299
