Subject [jira] [Commented] (YARN-1399) Allow users to annotate an application with multiple tags
Date Fri, 10 Jan 2014 22:08:51 GMT

    [ https://issues.apache.org/jira/browse/YARN-1399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13868378#comment-13868378

Vinod Kumar Vavilapalli commented on YARN-1399:

bq. It's unfortunate that we cannot restrict the API more by default, but we don't have a
choice without breaking things.
Actually there seems to be a choice. If folks are okay, the other option is to add a new API
with more restrictions, something like {{GetAppsWithTags}}. And then deprecate the current

BTW, getting this API right is very important because we have to keep the same semantics for
the historical applications too - YARN-925. Opening for apps for everyone-by-default is worse
with historical apps.

> 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.
