> This was noticed on a secure cluster where the namenode had an upper case hostname and
the following command was issued
> hadoop dfs -ls webhdfs://NN:PORT/PATH
> the above command failed because delegation token retrieval failed.
> Upon looking at the kerberos logs it was determined that we tried to get the ticket for
kerberos principal with upper case hostnames and that host did not exit in kerberos. We should
convert the hostnames to lower case. Take a look at HADOOP-7988 where the same fix was applied
on a different class.
> I have noticed this issue exists on branch-1. Will investigate trunk and branch-2 and
update accordingly.
