>                 Key: FLINK-9943
>                 URL: https://issues.apache.org/jira/browse/FLINK-9943
>             Project: Flink
>          Issue Type: New Feature
>          Components: Core
>    Affects Versions: 1.5.0, 1.5.1
>            Reporter: Chuanlei Ni
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.7.0
> 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.
