Subject [jira] [Commented] (HADOOP-15885) Add base64 (urlString) support to DTUtil
Date Tue, 30 Oct 2018 19:45:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16669241#comment-16669241

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

Right now my use case is a little different.
We are enabling security in RBF and now to access HDFS we need Kerberos tickets.
The problem is that we also need to access the data from Azure which does not have direct
access to the HDFS cluster.
So, we are using HttpFs in front of RBF to access the data.
Then, we get delegation tokens from HttpFs and access the data through 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.
