Description

NiFiAtlasHook collects the notification messages to be sent to Atlas in a list, but it does not clean up the list after committing the messages. So it is just growing and the same notifications are being sent to Atlas again and again. This will lead to communication slow-down, OOM and/or exceeding Kafka message size limit.
