kangpinghuang commented on issue #2610: linked schema change failed if the tablet has both alpha and beta rowet URL: https://github.com/apache/incubator-doris/issues/2610#issuecomment-569594827 The bug is that schema change use the default rowset type to create the output rowset, but if the default rowset type is Alpha, the source rowset type is beta, and if the schema change is linked schema change, it will fail to add beta rowset into alpha rowset because of incompatible rowset meta. what is more, the original reason to use default rowset type as output rowset type is to use schema change to convert rowset type. But now it failed when the schema change is linked schema change, so the normal schema change will keep the rowset type and the special schema change of modify storage format will directly convert the rowset from alpha to beta for some use cases.
