> FlinkRunner: Harness manager for connecting operators to SDK Harnesses
> ----------------------------------------------------------------------
>                 Key: BEAM-3673
>                 URL: https://issues.apache.org/jira/browse/BEAM-3673
>             Project: Beam
>          Issue Type: Sub-task
>          Components: runner-flink
>            Reporter: Ben Sidhom
>            Assignee: Aljoscha Krettek
>            Priority: Major
> SDK harnesses require a common set of gRPC services to operate. The role of 
> the harness manager is to provide a uniform interface that multiplexes data 
> streams and auxiliary data between SDK environments and operators within a 
> given job.
> Note that multiple operators may communicate with a single SDK environment to 
> amortize container initialization cost. Environments are _not_ shared between 
> different jobs.
> The initial implementation will shell out to local docker, but the harness 
> manager should eventually support working with externally-managed 
> environments (e.g., created by Kubernetes).
