WARNING: A GTID set check of the MySQL instance at 'g8214:3306' determined that it contains transactions that do not originate from the cluster, which must be discarded before it can join the cluster.

 

g8214:3306 has the following errant GTIDs that do not exist in the cluster:

a859bb20-18ab-11ef-ae14-005056ab76d4:1

 

WARNING: Discarding these extra GTID events can either be done manually or by completely overwriting the state of g8214:3306 with a physical snapshot from an existing cluster member. To use this method by default, set the 'recoveryMethod' option to 'clone'.

 

Having extra GTID events is not expected, and it is recommended to investigate this further and ensure that the data can be removed prior to choosing the clone recovery method.

 

Please select a recovery method [C]lone/[A]bort (default Abort): clone

Validating instance configuration at 192.168.169.214:3306...

 

This instance reports its own address as g8214:3306

 

Instance configuration is suitable.

NOTE: Group Replication will communicate with other members using 'g8214:3306'. Use the localAddress option to override.

 

A new instance will be added to the InnoDB Cluster. Depending on the amount of

data on the cluster this might take from a few seconds to several hours.

处理办法：

在各个节点中/etc/hosts添加各主机名解析，重新执行即可完成节点添加。
