-----------------------------------
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.
