Subject [jira] [Created] (YARN-7215) REST API to list all deployed services by the same user
Date Tue, 19 Sep 2017 18:47:02 GMT
Eric Yang created YARN-7215:
-------------------------------

             Summary: REST API to list all deployed services by the same user
                 Key: YARN-7215
                 URL: https://issues.apache.org/jira/browse/YARN-7215
             Project: Hadoop YARN
          Issue Type: Bug
          Components: api, applications
            Reporter: Eric Yang
            Assignee: Eric Yang


In Slider, it is possible to list deployed applications from the same user by using:

<code>
slider list
</code>

This API can help UI to display application and services deployed by the same user.
Apiserver does not have ability to list all applications/services at this time.  This API
requires fast response to list all applications because it is a common UI operation.  ApiServer
deployed applications persist configuration in HDFS similar to slider, but using directory
listing to display deployed application might cost too much overhead to namenode.  We may
want to use alternative storage mechanism to cache deployed application configuration to accelerate
the response time of list deployed applications.
