Subject [jira] [Commented] (YARN-1399) Allow users to annotate an application with multiple tags
Date Fri, 10 Jan 2014 22:30:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-1399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13868409#comment-13868409

Sandy Ryza commented on YARN-1399:

Switching to a new API seems a little overboard to me for the purpose of changing the default.
 I think the place that we most care about the default behavior is when humans, not programs,
are making these requests.  And my understanding is that 9 times out of 10 when a human is
making a request like this it will be through the command line, where we still can't change
the default behavior of "yarn app -list".  Also, what would this mean for the REST API?  /ws/v1/cluster/fetchapp
instead of /ws/v1/cluster/app?

> 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.
