Subject [jira] [Created] (HADOOP-12787) KMS SPNEGO sequence does not work with WEBHDFS
Date Tue, 09 Feb 2016 20:01:18 GMT
Xiaoyu Yao created HADOOP-12787:

             Summary: KMS SPNEGO sequence does not work with WEBHDFS
                 Key: HADOOP-12787
                 URL: https://issues.apache.org/jira/browse/HADOOP-12787
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao

This was a follow up of my [comments|https://issues.apache.org/jira/browse/HADOOP-12559?focusedCommentId=15059045&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15059045]
for HADOOP-10698.

It blocks a delegation token based user (MR) using WEBHDFS to access KMS server for encrypted
files. This might work in many cases before as JDK 7 has been aggressively do SPENGO implicitly.
However, this is not the case in JDK 8 as we have seen many failures when using WEBHDFS with
KMS and HDFS encryption zone.
