[jira] [Commented] (HADOOP-15885) Add base64 (urlString) support to
DTUtil
[ https://issues.apache.org/jira/browse/HADOOP-15885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16667429#comment-16667429 ]
Íñigo Goiri commented on HADOOP-15885:
--------------------------------------
I'm not sure what would be the interface here but currently we have:
{code}
dtutil append filename1 filename2 filenameoutput
{code}
One option would be to just support files with one base64 DT per line, so it would be adding:
{code}
[-format (java|protobuf|base64)]
{code}
Another option would be to follow what Azure has been doing with {{org.apache.hadoop.fs.azure.security.TokenUtils}} and just add an import option which would add the base64 token into a DT file.
[~mattpaduano], you have been working a bunch on the DTUtil; any thoughts on this?

> 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.
