------------------------------------
Summary: Remove job lifecycle methods from public JobMasterGateway
interface
Key: FLINK-7489
URL: https://issues.apache.org/jira/browse/FLINK-7489
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.4.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Priority: Minor
The {{JobMaster}} exposes its job lifecycle methods {{startJobExecution}} and
{{suspendExecution}} via its {{JobMasterGateway}} to the public. I think these
methods should not be exposed because it allows other components to affect the
job execution without proper reason. Only the {{JobManagerRunner}} should be
responsible for calling these methods and has direct access to the
{{JobMaster}} instance. Therefore, these methods can directly be implemented by
the {{JobMaster}} without exposing them via the {{JobMasterGateway}}.
