be.out里有多个hdfsOpenFile找不到hdfs路径的报错，be多次打出上面日志之后就会有crash. 日志里的hdfs path出于公司要求，我用xxx替换了。
去fe.audit.log找下这个sql: fb9b0c25-b29f-11ed-9ed1-fa163e6c0ff8
hdfs 文件路径找不到这个我理解其实是正常的，在读写并发场景下，hdfs的文件会rename，如果此时fe侧的元数据没有刷新，就会报路径找不到的错误, 后面hdfs的元数据刷新之后就可以重新找到了。fb9b0c25-b29f-11ed-9ed1-fa163e6c0ff8 这个sql 方便加下wx吗？我wx发你sql。wx: 17610907960
稍等下，有点事，过会加你
嗯呢，好滴，不着急。
抱歉，这块复现了下SQL，是我们自己对SR修改聚合下推触发了某个SQL 的 corner case导致的。感谢 @trueeyu的解答，
