What version of zookeeper are you running? First check to see if there is a znode for the "/admin/reassign_partitions" in zookeeper.
If so, you could try a graceful shutdown of the controller broker. Once the new controller leader elects on another broker look at zk the znode "/admin/reassign_partitions" for the reassignment operation should be gone. If not, you are going to have to remove it through the shell or executor or however you reliably and safely do that. Re-run the command again. I created a JIRA for this https://issues.apache.org/jira/browse/KAFKA-1665 issue once we can reproduce it we should fix it.
