Ravi Teja Chilukuri created YARN-6532:
-----------------------------------------
Summary: Allocated container metrics per applciation should be
exposed using Yarn & ATS rest APIs
Key: YARN-6532
URL: https://issues.apache.org/jira/browse/YARN-6532
Project: Hadoop YARN
Issue Type: Improvement
Components: ATSv2, resourcemanager, restapi
Reporter: Ravi Teja Chilukuri
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.
