> 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".
> Related Change:
>       1. LocalStreamEnvironment and RemoteStreamEnvironment can also execute 
> a job by the executors(LocalExecutor and RemoteExecutor).  Introduce 
> StreamGraphExecutor which executors a streamGraph as PlanExecutor executors 
> the plan.  StreamGraphExecutor and PlanExecutor all extend Executor.
>       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.
