Seems that this might be the reason why some groups cannot elect leaders as far 
as we get {{Failed to refresh a leader}} for some partitions groups, but we 
cannot get leader elected message like {{Node 
<a6328a6b-7da8-4a8f-a1b5-a27c75c6007b_part_4/172.17.0.6:3344> become leader of 
group}} for some partitions 

Note that you have to set replica to 1 for all tables that you create as far as 
there are some limitations on unstable topologies where leader could be 
reelected.

Seems that this might be the reason why some groups cannot elect leaders as far 
as we get {{Failed to refresh a leader}} for some partitions groups, but we 
cannot get leader elected message like {{Node 
<a6328a6b-7da8-4a8f-a1b5-a27c75c6007b_part_4/172.17.0.6:3344> become leader of 
group}} for some partitions 

Note that you have to set replica to 1 for all tables that you create as far as 
there are some limitations on unstable topologies where leader could be 
reelected.
