Hi I have by mistake created a topic with replication factor of 1. I am
trying to increase the replication, but I get the below error. Can anyone
please let me know if I am doing anything wrong. The Topic is created with
single partition(te_re-0).
./kafka-reassign-partitions.sh --zookeeper xxxx:2181 --command-config
kafka.properties --reassignment-json-file increase-replication-factor.json
-execute
