Subject [jira] [Commented] (HADOOP-12453) Support decoding KMS Delegation Token with its own Identifier
Date Wed, 02 Nov 2016 16:29:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15629488#comment-15629488
] 

Xiao Chen commented on HADOOP-12453:
------------------------------------

bq. The TOKEN_KIND/TOKEN_KIND_STR in KMSCP have been used by upstream projects ...
It's marked as {{@InterfaceAudience.Private}} so from hadoop's POV we should be free to change.
Best way I think is to mark the new KMSDT class public and let downstream use that.
All that said, I'm okay with the current patch since that's not within hadoop's control. +1
pending checkstyle fixes. Thanks Xiaoyu.

> kms-dt currently does not have its own token identifier class to decode it properly as
shown in the HDFS logs below. This JIRA is opened to add support for that.
