-------------------------------------
I'll take a look at this..
@Alejandro, can you please provide some more detail if you have on where the
extra element to the principal is getting added. Thanks!
> 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.
