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 API.
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.
