Currently hadoop-common is a JAR module, thus it cannot aggregate sub-modules.
Changing it to POM module it makes it an aggregator module, all the code under hadoop-common must be moved to a sub-module.
mv hadoop-common hadoop-common-project
mv hadoop-alfredo hadoop-common-project
hadoop-common-project/pom.xml is a POM module that aggregates common & alfredo
