Hi 从错误栈来看，是因为 `No enum constant org.apache.flink.table.types.logical.LogicalTypeRoot.ANY ` 这个导致的无法正常 restore。首先你需要看下是否是大版本的升级（像 Jark 说的那样），如果是小版本的升级，你需要看下为什么找不到这个 LocigcalTypeRoot.ANY.
PS: 贴代码/错误栈可以使用 gist[1] 或者 pastebin[2] 这样的服务，现在邮件里看到的栈信息没有很好的分行 [1] https://gist.github.com/ [2] https://pastebin.ubuntu.com/ Best, Congxian Jark Wu <[email protected]> 于2020年7月7日周二 下午4:28写道： > Hi, >
