----------------------------------
Summary: Support TaskManagerMetricQueryServicePaths msg in
JobManager Actor
Key: FLINK-9943
URL: https://issues.apache.org/jira/browse/FLINK-9943
Project: Flink
Issue Type: New Feature
Components: Core
Affects Versions: 1.5.1, 1.5.0
Reporter: Chuanlei Ni
Fix For: 1.6.0
The reasons are as follows
# AkkaJobManagerGateway wraps jm actor ref to support such functionality by
request RegisteredTaskManagers firstly and request task manager actor to get
metric query service path one by one. the procedure above is resource-wasted.
It will be more efficient if we support this functionality in the jm actor
# we can expose flink metric system directly to external system (such as flink
client and the like) to support more features in future. For now, metric system
has been exposed partially because Instance can not (and should not) be
transfered remotely. This feature will make metrics exposure consistent.
