I understand those 2 points. I was confused with the following comment.

So > Curator would fail to connect yet the ensemble is available. How can this timeout after 20 secs, if the connection timeout is 10 seconds? Also, So Curator would fail to connect yet the ensemble is available Can you explain the above statement then? As for my understanding, curator will try all Zookeeper nodes until it connects to an up and running zookeeper server or until the connection timeout. -Imesha On 2 November 2016 at 10:45, Cameron McKenzie <[email protected]> wrote: > Session timeout is a Zookeeper concept.
