Jordan Zimmerman commented on CURATOR-540:
------------------------------------------
[~honglun] "But the mode "StartMode.BUILD_INITIAL_CACHE" should not send
history, right?" - this is not correct. It won't send history about nodes it's
creating but connection state changes are always sent to the PathChildrenCache
listener. This has always been the case. If you want to avoid this, add a call
to {{client.blockUntilConnected(...)}} before starting the cache.
> BUILD_INITIAL_CACHE mode will post history child on start
