Jackie-Jiang opened a new pull request #8367: URL: https://github.com/apache/pinot/pull/8367
Fix #8324 The flakiness is caused by the following race condition: - The broker is removed from the IdealState - The broker is dropped from the cluster - The state transition message is created which recreates the ZK nodes for the dropped broker - The broker shows up again when querying the instances from the cluster The fix is to wait until ExternalView to converge before dropping the broker. The race condition itself is hard to fix as it is caused by Helix behavior. This PR enhances the drop instance rest API to still try to remove all instance ZK nodes even if instance config is already deleted so that there is a way to recover when the race condition happens. -- This is an automated message from the Apache Git Service.
