---------------------------------------
Summary: Support for listing all applications i.e /apps
Key: YARN-6058
URL: https://issues.apache.org/jira/browse/YARN-6058
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelinereader
Reporter: Rohith Sharma K S
Assignee: Rohith Sharma K S
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.
