Matthias Pohl commented on FLINK-28078:
---------------------------------------
It's not clear to me, yet, why we're not seeing the second ElectionDriver
taking over the leadership. I'd expect to get through the second iteration as
well because the leadership should be obtainable for the second ElectionDriver
as well.
