[jira] [Commented] (HADOOP-7988) Upper case in hostname part of the principals doesn't work with kerberos.

    [ https://issues.apache.org/jira/browse/HADOOP-7988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13191668#comment-13191668 ] 

Allen Wittenauer commented on HADOOP-7988:
------------------------------------------

Kerberos is case sensitive.  So if the local hostname returns upper case, this patch will likely break that machine from working.
