Thank you Manuel for your response. I tried the reassign partition tool and seen its not reliable. The problem with reassign partition tool kafka-reassign-partitions.sh is: it takes huge time in re-balancing each partition and during this time the entire cluster performance is impacted. When I ran this tool, it was stuck with one partition and it hung there for more than a day. The Cluster performance was severely impacted, and we had to restart the entire cluster. I don't see a way even to stop the tool when its taking long time. Can you please suggest how to overcome this situations.

I have a Kafka cluster of 3 nodes. I want to add 2 more nodes to the cluster to make it 5 node cluster. After adding the nodes, I will do a FULL CLUSTER RESTART. i.e., shutdown all kafka & zookeeper services at once and then start all the services in 5 nodes. I want to know 1. Does the FULL CLUSTER RESTART distribute the topic partitions evenly across 5 nodes? Or need to run the partition reassignment tool kafka-reassign-partitions.sh ? 2. Doesn't Kafka have internal mechanism to automatically reassign the partitions unless running kafka-reassign-partitions.sh Please clarify. Thank you.
