在sql实例执行语句报：
ERROR 40353 (HY000): Failed to begin transaction, RR isolation is only supported when global transaction is enabled
然后进入sdb shell
> db = new Sdb()
localhost:11810
Takes 0.029700s.
> db.updateConf({"mvccon":true})
(shell):1 uncaught exception: -264
One or more nodes did not complete successfully
Takes 0.204004s.
解决了吗兄弟
