Subject Re: Partitions reassignment is failing in Kafka 1.1.0
Date Sat, 30 Jun 2018 05:45:06 GMT
I am generating the reassignent.json like below

/home/ubuntu/deploy/kafka/bin/kafka-reassign-partitions.sh --zookeeper
127.0.0.1:2181 --generate --topics-to-move-json-file
/home/ubuntu/deploy/kafka/topics_to_move.json --broker-list '%s' |tail
-1 > /home/ubuntu/deploy/kafka/reassignment.json"

Then I am doing the reassignment using the generated file

/home/ubuntu/deploy/kafka/bin/kafka-reassign-partitions.sh --zookeeper
127.0.0.1:2181 --execute --reassignment-json-file
/home/ubuntu/deploy/kafka/reassignment.json

kafka-reassign-partitions.sh helps states

The JSON file with the partition reassignment configurationThe format to
> use is -

So it appears reassignment json that is generated by
kafka-reassign-partions.sh is creating an issue with logdirs. Is this some
issue in kafka-reassign-partitions.sh or some misconfiguration from my
side. ?
