>                 URL: https://issues.apache.org/jira/browse/YARN-6532
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: ATSv2, resourcemanager, restapi
>            Reporter: Ravi Teja Chilukuri
>            Priority: Minor
>
> Currently *allocatedMB* and *allocatedVCores* are being exposed by the RM and 
> ATS rest APIs.
> But we don't have the allocatedContainers exposed per application.
> This metric can be exposed as a additional param in the existing rest APIs.
> *RM:*  http://<rm http address:port>/ws/v1/cluster/apps/{appid}
> *ATS:* http(s)://<timeline server http(s) 
> address:port>/ws/v1/applicationhistory/apps/{appid}
> This would be essential for application types like TEZ, where there container 
> re-use.
