Beckham007 updated HADOOP-10773:
--------------------------------
Priority: Minor (was: Major)
> testLocalHostNameForNullOrWild() will failed if we have UpperCase hostname
> --------------------------------------------------------------------------
>
> Key: HADOOP-10773
> URL: https://issues.apache.org/jira/browse/HADOOP-10773
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.4.1
> Reporter: Beckham007
> Priority: Minor
>
> In the method getServerPrincipal() of SecurityUtil, we change the fqdn to
> lowcase. The testLocalHostNameForNullOrWild() of TestSecurityUtil will failed
> if the hostname contains uppercase.
> We could fix it simply change "String local =
> SecurityUtil.getLocalHostName();" to "String local =
> SecurityUtil.getLocalHostName().toLowCase();" in
> testLocalHostNameForNullOrWild().
> But I think we should rethink the implement of SecurityUtil.replacePattern().
> Is it need to hange the fqdn to lowcase?
