      Description

      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.

        When I've asked Eric Newton 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.

        I will try to look into this, but feel free to steal if someone finds cycles before I do.
