--------------------------------
Summary: Enhance JobManagerMetricGroup with FLIP-6 architecture
Key: FLINK-13732
URL: https://issues.apache.org/jira/browse/FLINK-13732
Project: Flink
Issue Type: Improvement
Components: Runtime / Metrics
Reporter: Biao Liu
Fix For: 1.10.0
This is a requirement from user mailing list [1]. I think it's reasonable
enough to support.
The scenario is that when deploying a Flink cluster on Yarn, there might be
several {{JM(RM)}} s running on the same host. IMO that's quite a general
scenario. However we can't distinguish the metrics from different
{{JobManagerMetricGroup}}, because there is only one variable "hostname" we can
use.
I think there are some problems of current implementation of
{{JobManagerMetricGroup}}. It's still non-FLIP-6 style. We should split the
metric group into {{RM}} and {{Dispatcher}} to match the FLIP-6 architecture.
And there should be an identification variable supported, just like {{tm_id}}.
