Subject [jira] [Commented] (YARN-7215) REST API to list all deployed services by the same user
Date Wed, 20 Sep 2017 04:44:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16172740#comment-16172740
] 

Jian He commented on YARN-7215:
-------------------------------

To clarify a bit more, the new YARN UI service tab already list the services, it does this
by passing a yarn-service type filter to the RM.  I meant to implement similar thing in CLI
to list services. Well, user can still get same result by passing a "yarn-service" filter
using "yarn application -list" command today. I think make it more explicit with a "yarn service
list" command would be more convenient to the user.

> 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.
