------------------------------
Summary: expose reserved memory/Vcores of nodemanager at webUI
Key: YARN-7690
URL: https://issues.apache.org/jira/browse/YARN-7690
Project: Hadoop YARN
Issue Type: New Feature
Components: yarn-ui-v2
Environment: now only total reserved memory/Vcores are exposed at RM
webUI, reserved memory/Vcores of a single nodemanager is hard to find out. it
confuses users that they obeserve that there are available memory/Vcores at
nodes page, but their jobs are stuck and waiting for resouce to be allocated.
It is helpful for bedug to expose reserved memory/Vcores of every single
nodemanager, and memory/Vcores that can be allocated( unallocated minus
reserved)
