Daryn Sharp reopened HADOOP-14146:
----------------------------------
Failing with java 7 due to java 8's Iterator having a default impl of remove. Will post addendum shortly.

> Key: HADOOP-14146
> URL: https://issues.apache.org/jira/browse/HADOOP-14146
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.5.0
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Fix For: 2.9.0, 3.0.0-alpha4, 2.8.2
>
> Attachments: HADOOP-14146.1.patch, HADOOP-14146.2.patch, HADOOP-14146.3.patch, HADOOP-14146.patch
>

> Many attempts (HADOOP-10158, HADOOP-11628, HADOOP-13565) have tried to add multiple SPN host and/or realm support to spnego authentication. The basic problem is the server tries to guess and/or brute force what SPN the client used. The server should just decode the SPN from the AP-REQ.
