Christopher Tubbs commented on ACCUMULO-3860:
---------------------------------------------
When I've asked [~ecn] about this test in the past, he basically indicated to
me that we don't really have a good way to predict how many there should be,
and that the test was just a sanity check to ensure we didn't do something to
cause it to shoot way up without noticing, and that it may need to be adjusted
over time if it doesn't reflect how many we're using.
So, I don't think that the fact that it got about 600 is really a problem. It
probably just means the test isn't a good test.

> Project: Accumulo
> Issue Type: Task
> Components: zookeeper
> Affects Versions: 1.7.0
> Reporter: Josh Elser
> Assignee: Josh Elser
> Fix For: 1.7.3, 1.8.1
>
>
> Noticed in ACCUMULO-3858 that the number of ZK watchers was sometimes being
> reported larger than expected.
> WatchTheWatchCountIT expected the watchers to be between 500 and 600, but, in
> debugging the test, I saw it sometimes above 600. Other times, it was happily
> in the expected range.
> Need to investigate to make sure nothing fishy is going on and we have a good
> understanding of how many watchers we are setting.
