> Key: STORM-1382
> URL: https://issues.apache.org/jira/browse/STORM-1382
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Reporter: Paul Poulosky
> Priority: Major
>
> The error message printed when a netty-client cannot connect to another worker is worded in a way that our users are interpreting as a failure with storm.
> There are times, such as at topology launch when such messages are normal as not all of the workers have been launched on all of the supervisors yet.
> Other times, it is indicative of a failure (uncaught exception, OOM) on another worker, but the end user believes that this client is failing, due to the error message.
> eg:
> {noformat}
> 2015-12-03 12:28:53.338 b.s.m.n.Client [ERROR] connection attempt 10 to Netty-Client-host1.grid.myco.com/10.1.2.3:6710 failed: java.net.ConnectException: Connection refused: host1.grid.myco.com/10.1.2.3:6710
> {noformat}
> We should change the message to be more informative to our end users as to what happened, and it should not be an ERROR, but a Warning, as there are occasions when one would expect to see this.
