Alejandro Abdelnur commented on HADOOP-10880:
---------------------------------------------
We could do it in a backwards compatible way:
* The new client side logic doing DT would use a header by default.
* The new client side logic doing DT would support a CONFIG switch to force
using the querystring (to support old services).
* The server logic doing DT will do header with fallback to querystring (to
support old clients).
> Move HTTP delegation tokens out of URL querystring to a header

> Key: HADOOP-10880
> URL: https://issues.apache.org/jira/browse/HADOOP-10880
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.4.1
> Reporter: Alejandro Abdelnur
> Assignee: Alejandro Abdelnur
>
> Following up on a discussion in HADOOP-10799.
> Because URLs are often logged, delegation tokens may end up in LOG files
> while they are still valid.
> We should move the tokens to a header.
> We should still support tokens in the querystring for backwards compatibility.
