Subject [jira] Commented: (MAPREDUCE-1005) why should not capacity sheduler jar not copied under lib during build
Date Fri, 18 Sep 2009 17:38:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1005?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12757281#action_12757281
] 

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.

> 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.
