Subject [jira] [Commented] (YARN-1399) Allow users to annotate an application with multiple tags
Date Wed, 04 Dec 2013 19:04:37 GMT

Robert Kanter commented on YARN-1399:

I am tempted to accept all unicode strings to begin with, and add restrictions if we really
need them. In this particular case of <h1>MapReduce</h1>, I think we should show
the user what he wants to see - it might not look good or consistent with rest of the page,
but that is what the user wanted. No?

It's generally a bad idea to not escape freeform user text when displaying it on a page; while
{{<h1>MapReduce</h1>}} is harmless, users could try to come up with more malicious
things...

> Nowadays, when submitting an application, users can fill the applicationType field to
facilitate searching it later. IMHO, it's good to accept multiple tags to allow users to describe
their applications in multiple aspects, including the application type. Then, searching by
tags may be more efficient for users to reach their desired application collection. It's pretty
much like the tag system of online photo/video/music and etc.
