   @dlmarion I don't anticipate us shipping a fix for 1.10, since doing so would likely break forward-compatibility with other 1.10 releases in the way things are persisted to ZK. This has been a constraint for a long time in 1.x, and I don't think it would be super urgent to fix for 1.10. There are some workarounds... such as creating watched missing entries and deleting them, so the delete causes the watches to trigger, or bouncing tservers with excessive watchers. This issue is assigned to @EdColeman  and I believe he is making progress in his fork on a more robust solution for 2.1 that, among other changes, involves using significantly fewer ZK nodes to store config.
