> Key: MAPREDUCE-2456
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2456
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: jobtracker
> Affects Versions: 0.20.204.0
> Reporter: Jeffrey Naisbitt
> Assignee: Jeffrey Naisbitt
> Priority: Trivial
> Fix For: 0.23.0
>
> Attachments: MAPREDUCE-2456-0.20s.patch, MAPREDUCE-2456-trunk.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> This jira is to provide more useful log information for debugging the "Too
> many fetch-failures" error.
> Looking at the JobTracker node, we see messages like this:
> "2010-12-14 00:00:06,911 INFO org.apache.hadoop.mapred.JobInProgress: Failed
> fetch notification #8 for task
> attempt_201011300729_189729_m_007458_0".
> I would be useful to see which reducer is reporting the error here.
> So, I propose we add the following to these log messages:
> 1. reduce task ID
> 2. TaskTracker nodenames for both the mapper and the reducer
