Subject Re: replica never takes leader role

This is not the desired behavior at all. I know there have been
improvements in this area since 4.8, but can't seem to locate the JIRAs.

I'm curious _why_ the nodes are going down though, is it happening at
random or are you taking it down? One problem has been that the Zookeeper
timeout used to default to 15 seconds, and occasionally a node would be
unresponsive (sometimes due to GC pauses) and exceed the timeout. So upping
the ZK timeout has helped some people avoid this...

FWIW,
Erick
