             Summary: Publishing maven package in com.hadoop namespace
                 Key: HADOOP-18223
                 URL: https://issues.apache.org/jira/browse/HADOOP-18223
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Will Norris


*I'm looking to get opinions on Twitter publishing the hadoop-lzo project on maven central in the com.hadoop namespace.*

Hey, I work in the open source office at Twitter, and we publish the [hadoop-lzo project|https://github.com/twitter/hadoop-lzo], which is used by a handful of folks. Some of you may know the history better than I, but this was an old project from Google Code that got migrated to Twitter's GitHub org years ago, and is currently published on our maven host at maven.twttr.com (and only there).

I don't know the full history of why it is only published there, but we've had a few incidents of that service being unavailable, [breaking builds for downstream users|https://github.com/twitter/hadoop-lzo/issues/148]. I'd like to remove this reliance on the maven.twttr.com host by publishing this on maven central.

Ideally, I'd like to do it in a way that requires the least amount of work for downstream users, which would mean using the existing group and project ID: com.hadoop.gplcompression.hadoop-lzo. The com.hadoop namespace is mostly unused on maven ([https://repo1.maven.org/maven2/com/hadoop/])... interestingly, only used by what I believe is another fork of the same compression library. But since hadoop.com is presumably owned by the Hadoop project (whois records are hidden, but it [appears to have always redirected|https://web.archive.org/web/*/hadoop.com] to the project website), I wanted to run this by someone associated with the project before we did this.

Is there any objection to us publishing this maven library into that namespace?  The alternative of course is to switch to a com.twitter namespace, but that would require more changes for downstream users.
