Subject [jira] [Created] (FLINK-7065) separate the flink-streaming-java module from flink-clients

Xu Pingyong created FLINK-7065:
----------------------------------

             Summary: separate the flink-streaming-java module from flink-clients 
                 Key: FLINK-7065
                 URL: https://issues.apache.org/jira/browse/FLINK-7065
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API
            Reporter: Xu Pingyong
            Assignee: Xu Pingyong


Motivation:
     It is not good that "flink-streaming-java" module depends on "flink-clients". Flink-clients
should see something in "flink-streaming-java".

Proposed Change:
      1. LocalStreamEnvironment and RemoteStreamEnvironment can also execute a job by the
executors(LocalExecutor and RemoteExecutor). 
      2. Introduce  StreamExecutionEnvironmentFactory which works similarly to ContextEnvironmentFactory
in flink-clients.
          When a object of ContextEnvironmentFactory, OptimizerPlanEnvironmentFactory or PreviewPlanEnvironmentFactory
is set into ExecutionEnvironment(by calling initializeContextEnvironment), the relevant
StreamEnvFactory is alsot set into StreamExecutionEnvironment. It is similar when calling
unsetContext.
