> uppercase namenode hostname causes hadoop dfs calls with webhdfs filesystem

> Key: HADOOP-8878
> URL: https://issues.apache.org/jira/browse/HADOOP-8878
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 1.0.3, 1.1.0, 1.2.0, 3.0.0
> Reporter: Arpit Gupta
> Assignee: Arpit Gupta
> Attachments: HADOOP-8878.branch-1.patch, HADOOP-8878.patch
>
>
> 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.
