Subject [jira] [Comment Edited] (YARN-6532) Allocated container metrics per application should be exposed using Yarn & ATS rest APIs

[~rohithsharma] , I wanted to get the total allocated containers of a application for analysing
the jobs, especially for Tez.
Currently for MR, we can get the approximate # of containers by maps+reduces count, but for
tez there is no mechanism like that.

> 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 which have container re-use.
