-------------------------------------
Summary: Make ClusterEntrypoint more modular
Key: FLINK-10411
URL: https://issues.apache.org/jira/browse/FLINK-10411
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.7.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.7.0
Currently, the {{ClusterEntrypoint}} is not very modular in the sense that it
cannot be really used for testing purposes (e.g. starting a {{Dispatcher}} with
a {{WebMonitorRestEndpoint}}). The problem is that the {{ClusterEntrypoint}}
combines too many responsibilities (creating the cluster services, starting the
cluster components and deciding on when to terminate the JVM process).
I suggest to make the structure more compositional, meaning to split up the
service generation from the cluster component start up. That way we could also
remove code duplication between the different {{ClusterEntrypoint}}
implementations.
