[jira] [Updated] (HADOOP-8884) DEBUG should be WARN for DEBUG util.NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError

     [ https://issues.apache.org/jira/browse/HADOOP-8884?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Anthony Rojas updated HADOOP-8884:
----------------------------------

    Attachment: HADOOP-8884.patch

-First pass changed the nativecodeloader.java to throw a warning instead of a debug message when attempting to load native-hadoop but fails loading.

- Local unit tests failed, this is my first patch and I may have missed something, any comments / feedback are appreciated
