If we have six brokers, and a topic has three partitions on broker 1, 2, 3. Now if I add another three partitions. Will they be evenly distributed to 1,2,3 or 4,5,6?
Evenly distributed on all six brokers. If I use reassignment tool in 0.81 with 0.8 broker, will that work and get around the bugs? Your broker also needs to be on 0.8.1 for it to work correctly.
