Prasanth J updated HIVE-8809:
-----------------------------
    Attachment: dep_itests_without_hadoop_2.txt
                dep_itests_with_hadoop_2.txt
                dep_without_hadoop_2.txt
                dep_with_hadoop_2.txt

Attaching the output of mvn dependency:tree with and without specify -Phadoop-2 
explicitly. The dependency tree looks exactly the same. One thing I am not sure 
is why hive shims common dependency tree is showing hadoop-core. Following 
dependency is not within a profile in hive/shims/commom/pom.xml
{code}
    <dependency>
      <groupId>org.apache.hadoop</groupId>
      <artifactId>hadoop-core</artifactId>
      <version>${hadoop-20.version}</version>
      <optional>true</optional>
    </dependency>
{code}

[~brocknoland] Any idea why?
Also how to check if the issue mentioned in HIVE-5755 does not happen? Atleast 
from dependency tree it doesn't seem to happen.

> Activate maven profile hadoop-2 by default

> For every maven command profile needs to be specified explicitly. It will be 
> better to activate "hadoop-2" profile by default as HIVE QA uses hadoop-2 
> profile. With this change both the following commands will be equivalent
> {code}
> mvn clean install -DskipTests
> mvn clean install -DskipTests -Phadoop-2
> {code}
