Gopal V commented on HIVE-10450: -------------------------------- [~mmccline]: I think the dummy operator aliases play into the .size() == 1 in this patch, for aliases which come via the broadcast edge. > More than one TableScan in MapWork not supported in Vectorization -- causes > query to fail during vectorization >
