Junkai Xue commented on HELIX-642:
----------------------------------
In ZKHelixManager, there is a function called isFlapping(). We persists
disconnection time for the ZK and define a flappingTimeWindows. If in the
flappingTimeWindow the disconnection times over max disconnection threshold as
we defined, will treat that ZK is unstable now.
> Disable the participant instance once it disconnected due to unstable ZK
