Subject Re: Help needed to understand zookeeper in solrcloud

synchronous update of state and a requirement of more than half the
zookeepers alive (and in sync) this makes it impossible to have a "split
brain" situation ie when you partition a network and get let's say 3 alive
on one side and 2 on the other.

In this case the 2 node networks stops serving request since it's not in
majority.
