ZOOKEEPER-2807: Flaky test: org.apache.zookeeper.test.WatchEventWhenAutoResetTest.testNodeDataChanged
This failure appears to be related to ZOOKEEPER-2024. When a follower is syncing with the leader and logging "the stuff that came in between the snapshot and the uptodate" we do not wait for those commits to hit the db before starting the follower.
In 3.6, we now have two separate queues in the CommitProcessor, it is possible that the follower can serve requests before all of the commits from the leader have been applied. In the case of this test failure we can set a watch in between a create and delete call. This patch makes sure that the "delete" call will be committed before attempting to handle a client's watcher request.
You can merge this pull request into a Git repository by running:
