>                 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.
