i think ACCUMULO-3218 may have bit us two days ago, due to the first
zookeeper
in the list being unavailable.
but, after a full restart, i don't think that situation applies - the
lighter-load zookeeper
was in the middle of the list - 600, 600, 250, 600, 600.
thanks,

Hey Jeff,
Take a look at [1] and see if the zookeeper balance issue mentioned
is applicable.

Subject: imbalance in number of zookeeper clients
sorry if this is a faq. i can't come up with a good google query to
find the answer.
how bad is it that four of our five zookeepers have 600-700 clients,
and one
has about 250?
i assumed that zookeeper or accumulo has some sort of natural
rebalancing property,
so it will all work itself out.
i've been resisting a full accumulo/zk restart.
and restarting the one zookeeper to see what happens has a big
unpleasant wake, too.
so
- will they eventually rebalance
- if not, how bad is it that four of them are working harder
thanks,
jeff
