Hong Tang commented on MAPREDUCE-1005:
--------------------------------------
Artifacts created by contrib projects are by-default copied to
${dist.dir}/contrib/${contrib.project}/. Are you saying they should not be?
Otherwise, if a particular project (like capacity scheduler) wants to override
the default behavior, it should modify its own build.xml to override the
package target.
> why should not capacity sheduler jar not copied under lib during build

> Key: MAPREDUCE-1005
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1005
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: build
> Affects Versions: 0.21.0
> Reporter: Iyappan Srinivasan
>
> Right now, the capacity-scheduler.jar is not getting copied under
> trunk/build/hadoop-mapred-0.21.0-dev/lib/. It stays in
> trunk/build/hadoop-mapred-0.21.0-dev/contrib/capacity-scheduler/hadoop-0.21.0-dev-capacity-scheduler.jar.
> Every time somebody tries to build the trunk, they have to copy this jar
> from contrib to lib manually.
> During any kind of build (ant binary, ant bin-package, ant package) , this
> jar file should also get copied to lib. If a person uses default or fair
> sheduler, he will not use it, but still there is no harm of it being in lib.
> If he uses capacity scheduler, then it gets used automatically. This manual
> copy should be avoided.
