Subject [jira] [Commented] (YARN-1399) Allow users to annotate an application with multiple tags
Date Sat, 28 Dec 2013 02:10:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-1399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13857916#comment-13857916

Vinod Kumar Vavilapalli commented on YARN-1399:
-----------------------------------------------

Tags are a way to filter or search for applications. Let's not conflate with their display
and allow users to give arbitrary formats.

I'd push for case-insensitive, limited-length, and may be just ASCII charset. It seems limiting,
but that's more than enough.

> 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.
