Use of version attribute in reassignment json of kafka-reassign-partitions.sh

[Koushik Chitta]

Hi,

What is the use/intention of version attribute in kafka-reassign-partitions.sh 
command ? I see the code(at least version 1.1) just ignores this attribute.

> bin/kafka-reassign-partitions.sh --zookeeper localhost:2181 
> --reassignment-json-file expand-cluster-reassignment.json --execute
Current partition replica assignment

{"version":1,
"partitions":[{"topic":"foo1","partition":2,"replicas":[1,2]},
              {"topic":"foo1","partition":0,"replicas":[3,4]},
              {"topic":"foo2","partition":2,"replicas":[1,2]},
              {"topic":"foo2","partition":0,"replicas":[3,4]},
              {"topic":"foo1","partition":1,"replicas":[2,3]},
              {"topic":"foo2","partition":1,"replicas":[2,3]}]
}


Thanks,
Koushik
