chaoyli commented on issue #337: Fix add Rollup bug URL: https://github.com/apache/incubator-doris/pull/337#issuecomment-440666720 I have review your code and core dump info carefully. It may be a little difficulty. 1. Adding rollup should not call LinkedSchemaChange Class. Because LinkedSchemaChange will not writer new data but create a hard link instead. It is not the semantics for adding rollup. 2. CHECK in add_column_statistics is valid aside from LinkedSchemaChange. A new method should to be figured out to address this problem. I will reproduce this bug in my machine, and help to address this.
