             Summary: Move Configuration runtime check for hadoop-site.xml to initialization
                 Key: HADOOP-14213
                 URL: https://issues.apache.org/jira/browse/HADOOP-14213
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Jonathan Eagles
            Assignee: Jonathan Eagles


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.
