Subject [jira] [Created] (YARN-3467) Expose allocatedMB, allocatedVCores, and runningContainers metrics on running Applications on RM Web UI
Date Wed, 08 Apr 2015 18:24:15 GMT
Anthony Rojas created YARN-3467:
-----------------------------------

             Summary: Expose allocatedMB, allocatedVCores, and runningContainers metrics on
running Applications on RM Web UI
                 Key: YARN-3467
                 URL: https://issues.apache.org/jira/browse/YARN-3467
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: webapp, yarn
    Affects Versions: 2.5.0
            Reporter: Anthony Rojas
            Priority: Minor


The YARN REST API can report on the following properties:

*allocatedMB*: The sum of memory in MB allocated to the application's running containers
*allocatedVCores*: The sum of virtual cores allocated to the application's running containers
*runningContainers*: The number of containers currently running for the application

Currently, the RM Web UI does not report on these items (at least I couldn't find any entries
within the Web UI).

It would be useful for YARN Application and Resource troubleshooting to have these properties
and their corresponding values exposed on the RM WebUI.
