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

             Summary: Modify the Flink valid socket port check to 0 to 65535.
                 Key: FLINK-14481
                 URL: https://issues.apache.org/jira/browse/FLINK-14481
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Network
            Reporter: ming li


In Flink, I found that Flink's socket port check is 'port >= 0 && port <= 65536.
{code:java}
checkArgument(serverPort >= 0 && serverPort <= 65536, "Invalid port number.");{code}
But in the process of binding the port, the valid port is 0 to 65535(A port number of zero will let the System pick up anephemeral port in a bin operation). Although the 65536 port will fail due to the port out of range when actually binding, Flink has already done a valid range check on the port, which seems to be very confusing. Should we modify Flink's port check to 0 to 65535?
