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

             Summary: Netty Client is closed but the Worker is already using 
that Client.
                 Key: STORM-2561
                 URL: https://issues.apache.org/jira/browse/STORM-2561
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core
    Affects Versions: 0.10.1
            Reporter: ryan.jin
         Attachments: ClientClosed.txt

The Worker 's Netty Client is been closed  and The field "closing" in 
backtype.storm.messaging.netty.Client has been updated  to "true".
{code:java}
@Override
    public void close() {
        if (!closing) {
            LOG.info("closing Netty Client {}", dstAddressPrefixedName);
            context.removeClient(dstAddress.getHostName(),dstAddress.getPort());
            // Set closing to true to prevent any further reconnection attempts.
            closing = true;
            waitForPendingMessagesToBeSent();
            closeChannel();
        }
    }
{code}

But the worker is already  using that Netty Client. Because of the field 
'closing' is true,  Connect in the Client will never reconnecting the target.

{code:java}
public void run(Timeout timeout) throws Exception {
            if (reconnectingAllowed()) {
             .....
             } else {
                close();
                throw new RuntimeException("Giving up to scheduleConnect to " + 
dstAddressPrefixedName + " after " +
                        connectionAttempts + " failed attempts. " + 
messagesLost.get() + " messages were lost");

            }
{code}

{code:java}
    private boolean reconnectingAllowed() {
        return !closing;
    }
{code}

So, How can me find the cause why Worker close the NettyClient while the 
NettyClient is just working.

The logs is uploaded to Attachments by command "cat 
stt-jstorm-spout-4-28-1497837924-worker-6709.log|grep '10.24.41.10:6710' > 
/tmp/ClientClosed.txt".

Please let me know any other useful logs  i can support.
