Publish hadoop-core to the apache repository with an appropriate POM file
-------------------------------------------------------------------------
Key: HADOOP-3305
URL: https://issues.apache.org/jira/browse/HADOOP-3305
Project: Hadoop Core
Issue Type: New Feature
Components: build
Affects Versions: 0.16.3, 0.16.2
Reporter: Steve Loughran
Priority: Minor
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.
