Sameer Paranjpye updated HADOOP-55:
-----------------------------------
Fix Version: 0.5
> map-reduce job overhead is too high
> -----------------------------------
>
> Key: HADOOP-55
> URL: http://issues.apache.org/jira/browse/HADOOP-55
> Project: Hadoop
> Type: Bug
> Components: mapred
> Versions: 0.2
> Reporter: Yoram Arnon
> Assignee: Sameer Paranjpye
> Priority: Minor
> Fix For: 0.5
>
> map-reduce job overhead is too high. Running a null map-reduce job, with no
> input, no intermediate data and no output, on a several-hundred node cluster,
> takes several minutes, rather than several seconds.
> Enhanced distribution, launching and monitoring mechanisms should reduce the
> overhead to levels that match human online patience for short jobs.
