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.
