Alejandro Abdelnur created HADOOP-8346:
------------------------------------------
Summary: Changes to support Kerberos with non Sun JVM
(HADOOP-6941) broke SPNEGO
Key: HADOOP-8346
URL: https://issues.apache.org/jira/browse/HADOOP-8346
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.0.0, 3.0.0
Reporter: Alejandro Abdelnur
Priority: Blocker
Fix For: 2.0.0
before HADOOP-6941 hadoop-auth testcases with Kerberos ON pass, *mvn test
-PtestKerberos*
after HADOOP-6941 the tests fail with the error below.
Doing some IDE debugging I've found out that the changes in HADOOP-6941 are
making the JVM Kerberos libraries to append an extra element to the kerberos
principal of the server (on the client side when creating the token) so
*HTTP/localhost* ends up being *HTTP/localhost/localhost*. Then, when
contacting the KDC to get the granting ticket, the server principal is unknown.
