Description

The root cause is for hive view, during cubing, kylin will materialize the view by creating an intermediate table(drop intermediate table first). The intermediate tables' name is like kylin_intermediate_{view_name}, that means jobs will create tables with the same name if the same view is referenced. So one job's intermediate table may be dropped by another job, in such cases, error like "table not found" will happen
