I verified that Brett said thru this code:
val (partitionsToBeReassigned, replicaAssignment) =
ReassignPartitionsCommand.parsePartitionReassignmentData(
"{\"version\":1,\"partitions\":[{\"topic\":\"metrics\",\"partition\"
:0,\"replicas\":[1,2]},{\"topic\":\"metrics\",\"partition\":1,\"replicas\"
:[2,3]},]}");
partitionsToBeReassigned was empty.
I think parsePartitionReassignmentData() should be improved to give better
error information.
