-------------------------------------

             Summary: Use Log.*(Object, Throwable) overload to log exceptions
                 Key: FLINK-7979
                 URL: https://issues.apache.org/jira/browse/FLINK-7979
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.4.0
            Reporter: Hai Zhou UTC+8
            Assignee: Hai Zhou UTC+8
            Priority: Critical
             Fix For: 1.5.0


I found some code that logging an exception, it converts the exception to 
string or call `.getMessage()`.

I think the better way is to use the Logger method overloads which take 
`Throwable` as a parameter.
