Chris Nauroth created HADOOP-9431:
-------------------------------------
Summary: TestSecurityUtil#testLocalHostNameForNullOrWild on
systems where hostname contains capital letters
Key: HADOOP-9431
URL: https://issues.apache.org/jira/browse/HADOOP-9431
Project: Hadoop Common
Issue Type: Bug
Components: security, test
Affects Versions: 3.0.0
Reporter: Chris Nauroth
Assignee: Chris Nauroth
{{TestSecurityUtil#testLocalHostNameForNullOrWild}} contains assertions about
the principal returned for a null or wildcard hostname. The logic in
{{SecurityUtil#getServerPrincipal}} converts the local hostname to lower-case.
The test method does not perform the same conversion though, so the test passes
on systems with a hostname containing no upper-case letters, but it fails if
the hostname does contain upper-case letters.
