-----------------------------------

             Summary: Define hadoop-1 properties outside of profile
                 Key: CRUNCH-367
                 URL: https://issues.apache.org/jira/browse/CRUNCH-367
             Project: Crunch
          Issue Type: Improvement
          Components: Core
            Reporter: Sean Griffin
            Assignee: Josh Wills
            Priority: Minor


There's nothing wrong with the way the crunch-parent POM is written, but it's not compatible
with Gradle because Gradle does not yet support parsing Maven profiles, and the hadoop-1 profile
(the one used during transitive dependency resolution by consumers of crunch) defines the
necessary versions for hadoop and hbase.

While admittedly a bug in Gradle, I think the crunch-parent POM can be modified to work around
this problem with little effort.  Instead of defining the hadoop.version, hbase.version, and
hbase.midfix properties in the hadoop-1 profile, just declare them in the main set of properties
at the top of the POM and override them in the hadoop-2 profile.  I tested this on a local
version of Crunch and it correctly resolves the right dependencies when both no profile and
the hadoop-2 profile are active.
