> Excessive logging by org.apache.hadoop.util.Progress when value is NaN
> ----------------------------------------------------------------------
>
> Key: HADOOP-11085
> URL: https://issues.apache.org/jira/browse/HADOOP-11085
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.6.0
> Reporter: Mit Desai
> Assignee: Mit Desai
> Fix For: 2.6.0
>
> Attachments: MAPREDUCE-6082.patch
>
>
> MAPREDUCE-5671 fixed the "illegal" progress values that do not fall into
> (0,1) interval when the progress value is given. Whenever illegal value was
> encountered, LOG.warn would log that incident.
> As a result, each of the task's syslog will be full of WARN [main]
> org.apache.hadoop.util.Progress: Illegal progress value found, progress is
> Float.NaN. Progress will be changed to 0
> Each input record will contribute to one line of such log, leading to most
> of the tasks' syslog > 1GB.
> We will need to change the log level to debug to avoid such excessive logging.
