      Description

      Job tracker currently prints out information on every split.

      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
      

      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.
