Andrew McNabb updated HADOOP-960:
---------------------------------
Issue Type: Wish (was: Bug)
> Incorrect number of map tasks when there are multiple input files
> -----------------------------------------------------------------
>
> Key: HADOOP-960
> URL: https://issues.apache.org/jira/browse/HADOOP-960
> Project: Hadoop
> Issue Type: Wish
> Affects Versions: 0.10.1
> Reporter: Andrew McNabb
>
> This problem happens with hadoop-streaming and possibly elsewhere. If there
> are 5 input files, it will create 130 map tasks, even if
> mapred.map.tasks=128. The number of map tasks is incorrectly set to a
> multiple of the number of files. (I wrote a much more complete bug report,
> but Jira lost it when it had an error, so I'm not in the mood to write it all
> again)
