Subject [jira] [Created] (RANGER-2370) Hadoop-common should be shaded in agents-common and agents-audit
Date Sat, 16 Mar 2019 21:05:00 GMT
Bolke de Bruin created RANGER-2370:
--------------------------------------

             Summary: Hadoop-common should be shaded in agents-common and agents-audit
                 Key: RANGER-2370
                 URL: https://issues.apache.org/jira/browse/RANGER-2370
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 1.2.0
            Reporter: Bolke de Bruin


Hadoop-common pulls in a lot of dependencies, particularly Guava, Jersey that are also often
used in other projects. Guava and Jersey are particularly notorious for being 'tough' dependencies
as they are not backwards compatible.

As 'ranger-plugin-common' and 'ranger-plugins-audit' are to be integrated with 3rd party services
this poses serious challenges. For example the Presto plugin (see linked issue) is currently
blocked due to the reliance of Presto on Jersey 2, while Hadoop/Ranger use Jersey 1.X.

An example of how to shade Hadoop Common can be found here: [https://github.com/gchq/hadoop-common-shaded/]
