    **(The sections below can be removed for hotfixes of typos)**
    
    ## What is the purpose of the change
    
    When I read `flink-scala` code, I found like the below code:
    
    ```scala
    import org.apache.flink.api.common.operators.Keys
    import Keys.ExpressionKeys
    ```
    
    So, I want to fix it, use the follow code:
    
    ```scala
    import org.apache.flink.api.common.operators.Keys.ExpressionKeys
    ```
