---------------------------------------
Summary: [ATSv2] "metrics" for YARN_CONTAINERS are displayed as
empty.
Key: YARN-5553
URL: https://issues.apache.org/jira/browse/YARN-5553
Project: Hadoop YARN
Issue Type: Bug
Reporter: Rohith Sharma K S
metrics for YARN_CONTAINER entity types are displayed as empty. For master
containers some values are displayed but for other containers randomly it
displays metric values.
I think the behavior is due to publishing of container metric in monitor thread
from NodeManager. There are 2 issues I observe is
# Some containers has metric values CPU-Memory, some are empty.
# The CPU-Memory values taken are from current usage which monitor thread
reports. But issue with it is *aggregationOp* is SUM. So Each time monitor
thread reported values is being added and give some bigger values. But ideally
it is not actual usage.
I think CPU-MEMORY metric values for yarn-containers entities should be
allocated values.
