spaces-X opened a new issue #3769:
URL: https://github.com/apache/incubator-doris/issues/3769
**Describe the bug**
Bitmap and Hll type can not be used with incorrect aggregate functions,
which will cause to BEs crush.
Add some logical checks in FE's ColumnDef#analyze to avoid creating tables
or changing schemas incorrectly.
- Keys never be bitmap or hll type
- Values with bitmap or hll type have to be associated with bitmap_union or
hll_union
*To Reproduce**
Bitmap or hll type without correct aggregate type bit_union or hll_union
Create Table sql likes the following:
Create Table: CREATE TABLE `xxx` (
`c_date` date NOT NULL COMMENT "date",
`user_id` **bitmap NULL** DEFAULT " " COMMENT "userid",
...
) ENGINE=OLAP
DUPLICATE KEY(`xx`)
