Sangjin Lee commented on YARN-451: ---------------------------------- I am pretty close to getting a patch ready for review on this. A quick question before that however: the proposed change contains changes in YARN (changes in message definition to carry this extra info, and subsequent UI changes) and mapreduce (mapreduce application providing this information). Should I create two sub-tasks (one for YARN and one for MAPREDUCE) and provide separate patches for them? > 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.
