Jitendra Nath Pandey commented on HADOOP-7988:
----------------------------------------------
The patch only tries to standardize that hadoop always uses lowercase in the
hostname part of the kerberos principal, making sure that kerberos always sees
lower case in the hostname part of the principals. The patch doesn't change the
hostname anywhere, only the principals used are affected.
Just for reference of a similar code, hbase code uses same SecurityUtil api
and explicitly converts the hostname to lowercase.
> Upper case in hostname part of the principals doesn't work with kerberos.
