error from adding a partition

[Yu, Libo]

Hi folks,

I got this error when I tried to test the partition addition tool.
bin/kafka-add-partitions.sh --partition 1 --topic libotesttopic --zookeeper 
xx.xxx.xxx.xx:yyyy
adding partitions failed because of 
kafka.admin.AdminUtils$.assignReplicasToBrokers(Lscala/collection/Seq;IIII)Lscala/collection/Map;
java.lang.NoSuchMethodError: 
kafka.admin.AdminUtils$.assignReplicasToBrokers(Lscala/collection/Seq;IIII)Lscala/collection/Map;
        at 
kafka.admin.AddPartitionsCommand$.addPartitions(AddPartitionsCommand.scala:90)
        at kafka.admin.AddPartitionsCommand$.main(AddPartitionsCommand.scala:68)
        at kafka.admin.AddPartitionsCommand.main(AddPartitionsCommand.scala)

Did I miss anything here? Thanks.

Regards,

Libo
