Arpit Gupta created HADOOP-8878:
-----------------------------------
Summary: uppercase hostname causes hadoop dfs calls with webhdfs filesystem to
fail
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
Reporter: Arpit Gupta
Assignee: Arpit Gupta
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.
