关于配置seata.service.grouplist的问题

问题1：
seata1.3.0客户端一定要配置 seata.service.grouplist.seata-server=xx.xx.xx.xx:8091
问题在于 seata集群以后这个位置应该怎么填写。
问题2：
seata1.1.0之后客户端已经支持用yaml文件替代xx.cong文件。可是配置了yaml后还是报错。

Start by reviewing the Seata client configuration entry points for seata.service.grouplist.seata-server and the YAML configuration mentioned in the issue. Reproduce both the clustered-server configuration question and the YAML error against the stated Seata versions. Done means the correct cluster value and the cause of the YAML failure are established and documented.
