Move the check for hadoop-site.xml to static initialization of the Configuration class.
Description
Each Configuration object that loads defaults checks for hadoop-site.xml. It has been long deprecated and is not present in most if not nearly all installations. The getResource check for hadoop-site.xml has to check the entire classpath since it is not found. This jira proposes to 1) either remove hadoop-site.xml as a default resource or 2) move the check to static initialization of the class so the performance hit is only taken once.
