Sangjin Lee commented on YARN-451: ---------------------------------- I think some information about the "app size" can be obtained through ApplicationResourceUsageReport. Specifically it has getNeededResources() and getNumUsedContainers() and getNumReservedContainers(). This could be a useful candidate for sizing the app in terms of resource demand. If I am not mistaken, AppInfo is the class that exposes the data for the app UI, and we could add a string or a couple of numbers individually to expose this information. Thoughts? > Add more metrics to RM page > --------------------------- > > Key: YARN-451 > URL: https://issues.apache.org/jira/browse/YARN-451 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.0.3-alpha > Reporter: Lohit Vijayarenu > Priority: Minor > > ResourceManager webUI shows list of RUNNING applications, but it does not > tell which applications are requesting more resource compared to others. With > cluster running hundreds of applications at once it would be useful to have > some kind of metric to show high-resource usage applications vs low-resource > usage ones. At the minimum showing number of containers is good option. -- This message is automatically generated by JIRA.
