Germán Blanco commented on ZOOKEEPER-1732:
------------------------------------------
That sounds good to me.
I still see option 3 as more straight for solving the problem, but it does
involve quite a mess with updating the protocol and test cases and so on for
such a corner case.
It seems that there are no more opinions on this.
Is it ok if I prepare a patch with the change in the leader election process
that you suggest?
The test case might be a bit tricky, do you have any suggestion for that?
