             Summary: Flink: Windowing does not work with streams from collections and the local execution environment
                 Key: FLINK-6350
                 URL: https://issues.apache.org/jira/browse/FLINK-6350
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Bowen Li
            Assignee: Bowen Li
             Fix For: 1.2.2


When using events via the {{fromCollection}} method of {{StreamExecutionEnvironment}}, window timing is not supported. The time windows close immediately.  

This is unfortunate because mocking events from collections and testing them locally is a powerful way to unit test stream processors.
