Subject [jira] [Updated] (YARN-9464) Support "Pending Resource" metrics in RM's RESTful API
Date Tue, 09 Apr 2019 03:47:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-9464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhankun Tang updated YARN-9464:
-------------------------------
    Description: 
Knowing only the "available", "used" resource is not enough for YARN management tools like
auto-scaler. It would be helpful to diagnose the cluster resource utilization if it gets "Pending
Resource" from RM RESTful APIs. In a certain extent, it represents how starving the applications
are.

Initially, we can add "pending resource" information in below two RM REST APIs:
{code:java}
RMnode:port/ws/v1/cluster/metrics
RMnode:port/ws/v1/cluster/metrics/nodes
{code}
