This does happen, if the two master crash at the same time(If there is only one master, it's easier to reproduce). Because currently we have multiple listeners that will listen the node changes. https://github.com/apache/dolphinscheduler/blob/cc9e5d5d34fcf2279b267cca7df37a9e80eeba07/dolphinscheduler-server/src/main/java/org/apache/dolphinscheduler/server/master/zk/ZKMasterClient.java#L217-L228 If this listener exeucte first, it will remove the node, and will cause Master stop, and execute QuartzExecutors.shutdown method to close the datasource. The main reason is that the listener has no order. Here is a related issue #5491 and related pr #5497 -- This is an automated message from the Apache Git Service.
