Xavier Fu created STORM-556:
-------------------------------

             Summary: netty Client  reconnect bug
                 Key: STORM-556
                 URL: https://issues.apache.org/jira/browse/STORM-556
             Project: Apache Storm
          Issue Type: Bug
    Affects Versions: 0.9.2-incubating
            Reporter: Xavier Fu
            Assignee: Xavier Fu


if a storm worker die then restarted and the nimbus  reassign the task on the restarted worker with same host:port， the upstream task will not reconnect the host:port and the topology will hang up。

because the connect has broken and netty Client flush timer 
if (null != channel && channel.isWritable()) {
                            flush(channel);
}
always false.
