------------------------------------

             Summary: FSDownload.unpack() uses local locale for FS case 
conversion, may not work everywhere
                 Key: YARN-3029
                 URL: https://issues.apache.org/jira/browse/YARN-3029
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.6.0
            Reporter: Steve Loughran


{{FSDownload.unpack()}} lower-cases filenames in the local locale before 
looking at extensions for, "tar, "zip", ..

{code}
String lowerDst = dst.getName().toLowerCase();
{code}

it MUST use LOCALE_EN for the locale, else a file .ZIP won't be recognised as a 
zipfile in a turkish locale cluster
