[jira] [Commented] (YARN-6058) Support for listing all applications
i.e /apps
[ https://issues.apache.org/jira/browse/YARN-6058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16396232#comment-16396232 ]
Haibo Chen commented on YARN-6058:
----------------------------------
This showed up while I was exploring replacing JHS with python scripts (will be YARN UI2-like thing) + ATSv2. This is no good story in ATSv2 that supports client retrieval of all jobs (flow->flow run-> apps does not work without user id).
I think in MR's use case, a limit param on the query would be good enough. The application id, in YARN's case, contains cluster timestamp + the current app counter that increments each time. We may be able to leverage that information to support time-range queries as well.

> Priority: Critical

> Primary use case for /apps is many execution engines runs on top of YARN example, Tez, MR. These engines will have their own UI's which list specific type of entities which are published by them Ex: DAG entities.
> But, these UI's do not aware of either userName or flowName or applicationId which are submitted by these engines.
> Currently, given that user do not aware of user, flownName, and applicationId, then he can not retrieve any entities.
> By supporting /apps with filters, user can list of application with given ApplicationType. These applications can be used for retrieving engine specific entities like DAG.
