阿里云E-MapReduce通过外部Mysql JDBC Catalog来创建异步物化视图，可以正常创建。但是查看刷新物化视图任务是失败状态，报错：java.lang.IllegalStateException: corrupted partition meta，且此时直接查询该外部表数据是空的（实际上有数据），问题类似github社区的此类反馈https://github.com/StarRo....

阿里云E-MapReduce中hive 任务能有解决办法吗？

阿里云E-MapReduce中hive 任务跑着跑着有时候yarn 某一个节点就会掉了，然后发现该节点ssh 都连不上，能有解决办法吗， Scheduler 配置的资源 32g内存最大能用 26g？看监控 cpu和内存资源都没跑满，但是该节点连不上去ssh ，如何排查呢
