org.fluentd.logger.sender.RawSocketSender java.net.ConnectException: Connection refused

[SwathiKak]

ScalaRawSocketSender -> open() shows exceptions with stacktrace when failed to connect to server. The behavior itself seems to have no problem. However, it is confusing in production and during tests. Observed "printStackTrace" message when server refused to connect. Could we suppress it please in production code 0.7.0 versionon-wards?

Reference Code: def open(): Unit = { try { connect() } catch { case e: IOException => LOG.severe(s"Failed to connect fluentd: $server") LOG.severe("Connection will be retried") e.printStackTrace() close() } }
