1.克隆消费组的offset（同一个集群）
代码语言：javascript
复制bin/mqadmin cloneGroupOffset -n 192.168.1.x:9876 -s SCANRECORD_GROUP -d my-tst-cloneoffset -t SCANRECORD
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
clone group offset success. srcGroup[SCANRECORD_GROUP], destGroup=[my-tst-cloneoffset], topic[SCANRECORD][baseuser@HZPL001180 rocketmq]$
验证：
代码语言：javascript
复制bin/mqadmin statsAll -t SCANRECORD -n 192.168.1.x:9876
