> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Affects Versions: 2.7.0
> Reporter: Varun Saxena
> Assignee: Varun Saxena
> Labels: BB2015-05-RFC
> Attachments: MAPREDUCE-5981.02.patch, MAPREDUCE-5981.patch

>
> Following map reduce logs can be changed to DEBUG log level as they appear
> too many times in the log file and are not that important for debugging.
> 1. In
> org.apache.hadoop.mapreduce.task.reduce.Fetcher#copyFromHost(Fetcher.java :
> 313), the second log is not required to be at info level. This can be moved
> to debug as a warn log is anyways printed if verifyReply fails.
> SecureShuffleUtils.verifyReply(replyHash, encHash, shuffleSecretKey);
> LOG.info("for url="+msgToEncode+" sent hash and received reply");
> 2. Thread related info need not be printed in logs at INFO level. Below 2
> logs can be moved to DEBUG
> a) In
> org.apache.hadoop.mapreduce.task.reduce.ShuffleSchedulerImpl#getHost(ShuffleSchedulerImpl.java
> : 381), below log can be changed to DEBUG
> LOG.info("Assigning " + host + " with " + host.getNumKnownMapOutputs() +
> " to " + Thread.currentThread().getName());
> b) In
> org.apache.hadoop.mapreduce.task.reduce.ShuffleScheduler.getMapsForHost(ShuffleSchedulerImpl.java
> : 411), below log can be changed to DEBUG
> LOG.info("assigned " + includedMaps + " of " + totalSize + " to " +
> host + " to " + Thread.currentThread().getName());
