Karthik Kambatla commented on YARN-1399:
----------------------------------------
Thanks Vinod. I agree with the suggestions, in general.
bq. Today getApplications() API returns the list of ALL applications whether
accessible or not. That's a bad default that I thought I filed a ticket about.
By default we should only return the apps of the current user. Then there
should be options to list all accessible apps (apps with view-acl), and then
finally all apps across all users.
How about adding a field (enum - visibility - own, viewable, all) in
GetApplicationsRequest to capture this, the default for this could be "own".
bq. This does break the existing getApplications() API which we can leave as is
- in any case, information about all the apps that are not accessible is
completely blacked out, so it just serves as a simple listing.
Instead of adding another API for getApplications with the restricted default
view, how about changing existing GetApplicationsRequest.newInstance() methods
to set the visibility to ALL? That way, we wouldn't change the behavior. We
could add newInstance methods to capture rest of the fields - currently, we
don't have newInstance methods for user, queue, etc.

> 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.
