>          Components: replication
>    Affects Versions: 0.9.0.0
>         Environment: centos 7.2

> We were trying to increase the replication factor on a test topic we've created. 
> We followed the documentation's instruction:
> http://kafka.apache.org/documentation.html#basic_ops_increase_replication_factor
> and received:
> ```
> Current partition replica assignment
> {"version":1,"partitions":[{"topic":"test","partition":0,"replicas":[1]}]}
> Save this to use as the --reassignment-json-file option during rollback
> Successfully started reassignment of partitions {"version":1,"partitions":[{"topic":"test"
> ,"partition":0,"replicas":["1","2","3"]}]}
> ```
> After that whenever we try verify, it is stuck on:
> ```
> Status of partition reassignment:
> Reassignment of partition [test,0] is still in progress
> ```
> - We tried restarting the cluster and it still did not work.
> - The topic has 1 partition
> - The zookeeper /admin/reassign_partitions znode is empty
