---------------------------------

             Summary: Unreliable kafka-reassign-partitions.sh affecting performance
                 Key: KAFKA-8916
                 URL: https://issues.apache.org/jira/browse/KAFKA-8916
             Project: Kafka
          Issue Type: Task
          Components: admin, config
    Affects Versions: 2.1.1
         Environment: CentOS 7
            Reporter: VinayKumar


Currently I have 3 node kafka cluster, and I want to add 2 more nodes to make it 5 node cluster.
 *After adding the nodes to cluster, I need all the topic partitions to be evenly distributed
across all the 5 nodes.
 **In the past, when I ran kafka-reassign-partitions.sh & kafka-preferred-replica-election.sh,
it ran for very long time, hung & made the cluster unstable. So I'm afraid to use this
method.


Can you please suggest the best & foolproof way to assign partitions among all the cluster
nodes.
