Building Giraph with Hadoop

I am trying to set up Giraph with Hadoop 2.7.1
Try as I might, it doesn't seem to work.
I have tried following the below links,

https://blog.cloudera.com/blog/2014/02/how-to-write-and-run-giraph-jobs-on-hadoop/
http://lab.hypotheses.org/1207
What happens when I try to build using mvn -Phadoop_yarn -Dhadoop.version=2.7.1 -DskipTests package
hadoopuser:/usr/local/giraph$ mvn -Phadoop_yarn -Dhadoop.version=2.7.1 -DskipTests package

Edit:
As was suggested by Steve Kaeser in his answer I changed my pom.xlm and changed part is shown below.
<properties>

<munge.symbols>PURE_YARN</munge.symbols>

<giraph.maven.dependency.plugin.skip>true</giraph.maven.dependency.plugin.skip>
<giraph.maven.duplicate.finder.skip>true</giraph.maven.duplicate.finder.skip>
</properties>
After doing this when I run mvn -Phadoop_yarn -Dhadoop.version=2.7.1 -DskipTests install I get a lot of output and it fails. Parts of the output are shown below,

I ran into this issue today. Finally I needed two patches to fix it:
Open pom.xml in base directory and replace <munge.symbols>PURE_YARN,STATIC_SASL_SYMBOL</munge.symbols> with: <munge.symbols>PURE_YARN</munge.symbols>
Apply patch found here: GIRAPH-1110.02.patch
Build using the clean flag of maven: mvn -Phadoop_yarn -Dhadoop.version=2.7.3 clean package -DskipTests

I just ran into this issue earlier today and found a reply in the mailing list that suggests removing STATIC_SASL_SYMBOL from munge.symbols in the hadoop_yarn profile.
I was able to build that profile after making that change.
Here is the link to the mailing list archive: http://mail-archives.apache.org/mod_mbox/giraph-user/201501.mbox/%3C54B17196.4040107#hiro-tan.org%3E

gwt-maven-plugin not finding sources in a maven module in a GWT maven reactor build

I have the goal of creating a maven reactor build for a modular RequestFactory project. I'm using Thomas Broyer's maven archetype as suggested by him in GWT Code Server not finding a module in a newly generated project using a maven archetype,
Thanks to his effort, it works immediately out of the box and without any problems whatsoever. It creates three modules (with names ending in client, server, shared).
What bugs me is that three projects have their java sources in the same package. One of the things I tried to do, after the project was up and running, was to refactor the packages of the three maven modules to actually end in their respective names. This works for all but the client project, since the GWT compiler (gwt-maven-plugin) does not seem to look for sources outside of the client project's own package when building the client package.
Hence, if the shared project has it's own package that is not a subpackage of the client's, this will result in GWT not being able to resolve all sources in shared.
My question is, am I missing something obvious, or am I trying to do something that is not recommended at all? Any pointers would be greatly appreciated.
I have been toying around with GWT and maven for a while now, but am still no expert so please bear with me :-). Here is what I did in detail:
Created the project using Thomas Broyer's archetype (the first time I selected "N" in order to be able to input a module name different than "App" the second time):

There is nothing else in the pom.xml and source files that appears in need to be changed. All Java compilations work out perfectly. However, the end result is a fail, since the GWT compiler (gwt-maven-plugin) does not seem to look for sources outside of the client project's own package when building the client package. Hence, if the shared project has it's own subpackage that is not a subpackage of the client's this will result in gwt-maven-plugin not being able to resolve any sources in shared.
So anything that is under shared is not found by the GWT compiler. Interestingly, if I rename the package in my-modular-app-shared to com.example.my.modular.app.client instead of com.example.my.modular.app.shared and update the references, everything works as a charm.
It seems to me that the problem is that gwt-maven-plugin is confined to the package of the client and all other referenced projects ought to have all GWT relevant sources in subpackages of the client package. The question is, how can I tell the GWT compiler to look in a different package when traversing different maven modules?
Any help/pointers greatly appreciated, and thanks in advance!
PS: I managed to create a workaround by adding the following GWT module in the client project (package com.example.my.modular.app) and inheriting it in the MyModularApp.gwt.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC
"-//Google Inc.//DTD Google Web Toolkit 1.6.4//EN"
"http://google-web-toolkit.googlecode.com/svn/tags/2.4.0/distro-source/core/src/gwt-module.dtd">
<module>
<source path="shared"/>
</module>
So to rephrase the question: there an automatic way of achieving this instead of having the need to declare artificial modules?

This is just how GWT works, the compiler only sees classes from the source path which is a subset of the classpath.
Generally, people put their gwt.xml in the com.example.my.modular.app package and add client and shared subpackages to the source path:
<source path="client"/>
<source path="shared"/>

I would recommend to start fixing your pom with the first lines:
[WARNING]
'build.plugins.plugin.(groupId:artifactId)' must be unique but found duplicate declara
tion of plugin org.liquibase:liquibase-maven-plugin # line 132, column 21
[WARNING] 'build.plugins.plugin.(groupId:artifactId)' must be unique but found duplicate declara

[WARNING]
[WARNING] Some problems were encountered while building the effective model for org.mifos:mifos-
accounting:jar:1.8-SNAPSHOT
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-war-plugin is missin
g. # line 29, column 21
[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of
your build.
[WARNING]
After you fixed that i can see that based on this message:
on project mifos-db: Error setting up or running Liquibase: java.sql.SQLException: Access
denied for user 'mifos'#'localhost' (using password: YES)
That you are trying to access a database which does not allow a password in relationship with this user (Assuming MySQL ?). You have to fix the permissions for this user.
