kennknowles opened a new issue, #18723: URL: https://github.com/apache/beam/issues/18723
I've seen failures a bit today. Here is one: [https://builds.apache.org/job/beam_PreCommit_Java_GradleBuild/1758/testReport/junit/org.apache.beam.sdk.io.mqtt/MqttIOTest/testReadNoClientId/](https://builds.apache.org/job/beam_PreCommit_Java_GradleBuild/1758/testReport/junit/org.apache.beam.sdk.io.mqtt/MqttIOTest/testReadNoClientId/) Filing all flakes as "Critical" priority so we can sickbay or fix. Since that build will get GC'd, here is the Standard Error. It looks like from that perspective everything went as planned, but perhaps the test has a race condition or something? ``` Feb 01, 2018 11:28:01 PM org.apache.beam.sdk.io.mqtt.MqttIOTest startBroker INFO: Finding free network port Feb 01, 2018 11:28:01 PM org.apache.beam.sdk.io.mqtt.MqttIOTest startBroker INFO: Starting ActiveMQ brokerService on 57986 Feb 01, 2018 11:28:03 PM org.apache.activemq.broker.BrokerService doStartPersistenceAdapter INFO: Using Persistence Adapter: MemoryPersistenceAdapter Feb 01, 2018 11:28:04 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:1) is starting Feb 01, 2018 11:28:04 PM org.apache.activemq.transport.TransportServerThreadSupport doStart INFO: Listening for connections at: mqtt://localhost:57986 Feb 01, 2018 11:28:04 PM org.apache.activemq.broker.TransportConnector start INFO: Connector mqtt://localhost:57986 started Feb 01, 2018 11:28:04 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:1) started Feb 01, 2018 11:28:04 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: For help or more information please see: http://activemq.apache.org Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService stop INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:1) is shutting down Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.TransportConnector stop INFO: Connector mqtt://localhost:57986 stopped Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService stop INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:1) uptime 24.039 seconds Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService stop INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:1) is shutdown Feb 01, 2018 11:28:26 PM org.apache.beam.sdk.io.mqtt.MqttIOTest startBroker INFO: Finding free network port Feb 01, 2018 11:28:26 PM org.apache.beam.sdk.io.mqtt.MqttIOTest startBroker INFO: Starting ActiveMQ brokerService on 46799 Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService doStartPersistenceAdapter INFO: Using Persistence Adapter: MemoryPersistenceAdapter Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:2) is starting Feb 01, 2018 11:28:26 PM org.apache.activemq.transport.TransportServerThreadSupport doStart INFO: Listening for connections at: mqtt://localhost:46799 Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.TransportConnector start INFO: Connector mqtt://localhost:46799 started Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: Apache ActiveMQ 5.13.1 (localhost, ID:115.98.154.104.bc.googleusercontent.com-38646-1517527683931-0:2) started Feb 01, 2018 11:28:26 PM org.apache.activemq.broker.BrokerService doStartBroker INFO: For help or more information please see: http://activemq.apache.org Feb 01, 2018 11:28:28 PM org.apache.beam.sdk.io.mqtt.MqttIOTest lambda$testRead$1 INFO: Waiting pipeline connected to the MQTT broker before sending messages ...
