-----------------------------------------
Summary: Create a JobClient for job control and monitoring
Key: FLINK-4272
URL: https://issues.apache.org/jira/browse/FLINK-4272
Project: Flink
Issue Type: New Feature
Components: Client
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 1.2.0
The aim of this new features is to expose a client to the user which allows to
cancel a running job, retrieve accumulators for a running job, or perform other
actions in the future. Let's call it {{JobClient}} for now (although this
clashes with the existing JobClient class which could be renamed to
JobClientActorUtils instead).
The new client should be returned from the {{ClusterClient}} class upon job
submission. The client should also be instantiatable by the users to retrieve
the JobClient with a JobID.
We should expose the new JobClient to the Java and Scala APIs using a new
method on the {{ExecutionEnvironment}} / {{StreamExecutionEnvironment}} called
{{executeWithControl()}} (perhaps we can find a better name).
