Subject [jira] [Commented] (HADOOP-10880) Move HTTP delegation tokens out of URL querystring to a header
Date Wed, 06 Aug 2014 20:28:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14088198#comment-14088198

Daryn Sharp commented on HADOOP-10880:

I was assuming the plan was to use http authentication itself.   The RFC defined method DIGEST
(circa late 90s) prevents sending the password over the wire in plain text.  I'm pretty sure
the SASL DIGEST-MD5 client we use at the RPC layer is emitting exactly what goes in the headers
during the exchange.

It's also not going to play nice with HA tokens...

>         Attachments: HADOOP-10880.patch
> 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.
