Alejandro Abdelnur commented on HDFS-3460:
------------------------------------------
the failure seems unrelated and a one off, I cannot reproduce it in my
environment, if I see it again in Jenkins I'll open a JIRA as a flaky test to
fix.
the patch does not have testcase that verifies the change, I've verified the
change in a Kerberos deployment using a service principal.
> HttpFS proxyuser validation with Kerberos ON uses full principal name

> The HttpFSServer.getEffectiveUser() method uses the principal name for proxy
> user verification. If the Kerberos is ON and the proxy user is a service
> principal (NAME/HOST) then the verification fails, instead the short name
> (just NAME) should be used.
