> It cause us very confused about it : if we write some big data into
> zookeeper. Thus. we found, in actual. it is just the log/issue when closing
> the server when reelecting the leader.
> So I think we can do one tiny code change to avoid throw the error which
> causing confuse with big size's data to reduce trouble shooting effort.
