[jira] [Created] (MAPREDUCE-4308) Remove excessive split log messages

Kihwal Lee created MAPREDUCE-4308:
-------------------------------------

             Summary: Remove excessive split log messages
                 Key: MAPREDUCE-4308
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4308
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobtracker
    Affects Versions: 1.0.3
            Reporter: Kihwal Lee
             Fix For: 1.1.0


Job tracker currently prints out information on every split.

{noformat}
2012-05-20 00:06:01,985 INFO org.apache.hadoop.mapred.JobInProgress: 
tip:task_201205100740_1745_m_000000 has split on node:/192.168.0.1
/my.totally.madeup.host.com
{noformat}

I looked at one cluster and these messages were taking up more than 30% of the JT log. If jobs have large number of maps, it can be worse. I think it is reasonable to lower the log level of the statement from INFO to DEBUG.
