Arpit Gupta created HADOOP-8882:
-----------------------------------

             Summary: uppercase namenode host name causes fsck to fail when 
useKsslAuth is on
                 Key: HADOOP-8882
                 URL: https://issues.apache.org/jira/browse/HADOOP-8882
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Arpit Gupta
            Assignee: Arpit Gupta


{code}
 public static void fetchServiceTicket(URL remoteHost) throws IOException {
    if(!UserGroupInformation.isSecurityEnabled())
      return;
    
    String serviceName = "host/" + remoteHost.getHost();
{code}

the hostname should be converted to lower case. Saw this in branch 1, will look 
at trunk and update the bug accordingly.
