Subject [jira] [Commented] (HADOOP-15885) Add base64 (urlString) support to DTUtil
Date Tue, 30 Oct 2018 17:49:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16669118#comment-16669118
] 

Íñigo Goiri commented on HADOOP-15885:
--------------------------------------

BTW, currently we have the configuration {{hadoop.token.files}} and {{HADOOP_TOKEN_FILE_LOCATION}}.
Should we also add an option to pass a base64 token as a configuration key ({{hadoop.token}})
or an environment variable ({{HADOOP_TOKEN}})?
This is similar to what Azure allows with the token:
http://hadoop.apache.org/docs/current/hadoop-azure/index.html#Delegation_token_support_in_WASB
Actually, the approach described there would also work for regular WeBHDFS.

> HADOOP-12563 added a utility to manage Delegation Token files. Currently, it supports
Java and Protobuf formats. However, When interacting with WebHDFS, we use base64. In addition,
when printing a token, we also print the base64 value. We should be able to import base64
tokens in the utility.
