Description

Noticed the following during compilation:

[WARNING] /flink/flink-streaming-scala/src/main/scala/org/apache/flink/streaming/api/scala/WindowedStream.scala:33: warning: imported `OutputTag' is permanently      hidden by definition of object OutputTag in package scala
[WARNING] import org.apache.flink.util.{Collector, OutputTag}
[WARNING]                                          ^
[WARNING] /flink/flink-streaming-scala/src/main/scala/org/apache/flink/streaming/api/scala/WindowedStream.scala:33: warning: imported `OutputTag' is permanently      hidden by definition of class OutputTag in package scala
[WARNING] import org.apache.flink.util.{Collector, OutputTag}

We should avoid the warning e.r.t. OutputTag.

There may be other occurrences of similar warning.
