             Summary: setup_quickstart hanging
                 Key: FLINK-9298
                 URL: https://issues.apache.org/jira/browse/FLINK-9298
             Project: Flink
          Issue Type: Bug
            Reporter: Alex Chen


Well, I follow tutorial 
([https://ci.apache.org/projects/flink/flink-docs-master/quickstart/setup_quickstart.html)].
 Regardless there are several typos like log files name incorrect, flink was 
hanging executing `

bin/flink run examples/streaming/SocketWindowWordCount.jar --port 9000`, looks 
like:

 

```

➜  build-target git:(master) bin/flink run 
examples/streaming/SocketWindowWordCount.jar --port 9000

Starting execution of program

(hanging)

```

Below are logs
