We frequently get ClosedSelectorException from our KafkaSpout implementation on
topology shutdown. We are using storm-kafka-client version 1.2.1 and
kafka-clients version 0.10.2.0. The reason for the older version of
kafka-clients is https://issues.apache.org/jira/browse/STORM-3102. We want to
look into building storm-kafka-client 1.2.3 locally until it is released, but
would this prevent the ClosedSelectorException from occurring? Or is there a
different cause for this exception? The exception trace is:
2019-05-04 11:34:38,420 ERROR executor [Thread-72-customKafkaSpout-executor[19
