Description

By default maven-project-info-reports-plugin is called at site phrase but in Hadoop Main's pom we use excludeDefaults tag which excludes maven-project-info-reports-plugin from the process. It will run only when it is called directly.
I found two invocation: hadoop-hdfs-httpfs and hadoop-auth.
These invocations seems unnecessary as I pointed in HADOOP-14393.

This plugin can be removed. Makes the understanding of site generation harder. It took me a while finding out the role of the plugin.
