Giridharan Kesavan updated HADOOP-3305:
---------------------------------------
Attachment: rmlib.sh
HADOOP-3305.patch
This patch is developed from the patch submitted by Steve, Thanks to Steve.
With this patch we should be able to use ivy to resolve dependencies through
the maven repository, and we can get rid of the local lib folder when all the
dependencies all available on the m2 repository.
As Steve mentioned there are certain missing libraries in the m2 repo.
Those missing dependencies are still added to the classpath from the local lib
folder, and other dependencies that are available in the m2 repository are
resolved/retrieved by IVY from the maven repository.
Here I 've provided the list of missing dependencies for different component.
*Hadoop-core*
-commons-cli-2.0-SNAPSHOT.jar - 20040117.000000 snapshot available..
-kfs-0.2.2.jar - NOT AVAILABLE
*Thrift*
-hadoopthriftapi.jar - NOT AVAILABLE
-libthrift.jar - NOT AVAILABLE
*Chukwa*
-json.jar - Not sure fo the jar file version though json is
available in the m2 respo.
This patch contains a new set of ivybuild.xml & ivy.xml files for diff comps
which resembles the existing buid.xml files except for the ivy implementations.
The ivy.xml file has all the dependencies for diff components listed in it with
versions
pulled out from the corresponding components libraries.properties file.
Also this patch contains a top level ivysettings.xml file which has the details
of all the resolvers and the url for resolving the dependencies.
*Instruction to test the patch*
Apply the patch
run the rmlib.sh script from hadoop-core base folder.
_[ This would remove the local lib folder with jar files that can be
resolved/retrieved from the m2 repository]_
As of now the patch supports *3 main targets*
*compile
*package
*releaseaudit
To execute the targets
{quote}
ant -f ivybuild.xml releaseaudit
{quote}
This has compile and package targets as dependencies.
Work in progress for other ant targets. Meanwhile I would like to get this
patch reviewed.
Please review this patch.
Thanks,
Giri

> Key: HADOOP-3305
> URL: https://issues.apache.org/jira/browse/HADOOP-3305
> Project: Hadoop Core
> Issue Type: New Feature
> Components: build
> Affects Versions: 0.16.2, 0.16.3
> Reporter: Steve Loughran
> Priority: Minor
> Attachments: HADOOP-3305.patch, hadoop-core-0.16.2.pom,
> ivy-support-first-pass.zip, rmlib.sh
>
>
> To let people downstream build/test with hadoop, using Apache Ivy or Apache
> Maven2 to pull it down, hadoop-core needs to be published to the apache
> repository with a .pom file that lists its mandatory dependencies.
> In an automated build process, this means
> -having a template XML pom defining all included dependencies (and excluded
> transient dependency artifacts)
> -having a property file driving version numbering of all artifacts
> -copying this template with property expansion to create the release POM file
> -public releases only: sticking this POM file up on people.apache.org in the
> right place, along with the JAR and some .md5 checksums
> There's a risk that if the hadoop team dont do this, someone else will (as
> mahout are doing under
> http://people.apache.org/~kalle/mahout/maven2/org/apache/hadoop/ )
> This is bad as hadoop end up fielding the support calls from someone elses
> files.
> Before automating the process, existing hadoop-core JARs can be pushed out
> with hand-encoded POM files. The repository police dont allow pom files ever
> to be changed, so supporting existing releases (.16.2, 0.16.3 ... ) is a way
> of beta testing the POMs.
