Zhijie Shen commented on YARN-1399:
-----------------------------------
Hm... It makes sense. The only tag from oozie seems not to be enough to
identify the apps of a workflow. For example, in the multiple tenancy
situation, two oozie workflows submitted by two different users happen to have
the same workflow ID. Then, killing the apps have this workflow ID will screw
up both workflow.
To solve the problem in YARN-1390, we may need more information to identify the
apps belonging to a unique workflow:
1. Having GUID in the workflow ID to prevent conflicting IDs in a YARN cluster
(unless others intentionally attack)
2. Check owner of the application as well to avoid the case that attackers copy
the workflow ID.

> 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.
