Running DBT on MacOS with dbt-clickhouse does not support renameat2()

[LPauzies]

Describe the bug

When running : dbt run --target=clickhouse-dev --select=dbt_mart on MacOS Sonoma 14.6.1 (MacBook Pro (13-inch, M1, 2020))

08:27:45  Running with dbt=1.7.17
08:27:46  Registered adapter: clickhouse=1.7.7
08:27:46  Found 65 models, 3 seeds, 280 tests, 85 sources, 0 exposures, 0 metrics, 942 macros, 0 groups, 0 semantic models
08:27:46  
08:27:48  dbt_clickhouse adapter: ClickHouse server does not support the EXCHANGE TABLES command
08:27:48  dbt_clickhouse adapter: This can be caused by an obsolete ClickHouse version or by running ClickHouse on
08:27:48  dbt_clickhouse adapter: an operating system that does not support the low level renameat2() system call.
08:27:48  dbt_clickhouse adapter: Some DBT materializations will be slower and not atomic as a result.
08:27:49  dbt_clickhouse adapter: Unexpected server exception dropping table
08:27:49  
08:27:49  Finished running  in 0 hours 0 minutes and 2.68 seconds (2.68s).
08:27:49  Encountered an error:
Database Error
  'NoneType' object has no attribute 'version_major'
make: *** [dbt-run] Error 2

With :

• clickhouse : 23.8.4.69
• dbt-clickhouse : 1.7.7
• dbt-core : 1.7.17

While the same code is running perfectly in Linux distributions.

Steps to reproduce

1. Get a MacOS Sonoma 14.6.1
2. Create a DBT project
3. Create a clickhouse-server instance with version 23.8.4.69
4. Create a connection profile for this instance called "my_profile"
5. Create a dummy model called "my_mart" in the DBT project
6. Execute dbt run --target=my_profile --select=my_mart

Expected behaviour

A correct DBT materialization

Please run dbt with debug option to see full logs or look into ClickHouse query log to see the error

dbt run --target=clickhouse-dev --select=dbt_mart --debug
or
SELECT query, exception FROM system.query_log WHERE exception != '' and event_time ...

Thanks @simpl1g for the response, here is a more detailed stack trace of the failed execution.

[genzgd]

the rename2 message is just information. This is almost certainly an unrelated bug. Can you create a small reproducible example from your project?

[genzgd]

I don't understand why these messages don't print more details :(

13:09:20  dbt_clickhouse adapter: Unexpected server exception dropping table
13:09:20  dbt_clickhouse adapter: Error running SQL: macro list_schemas

Is there anything in the ClickHouse server logs that shows some DROP related exception?

[LPauzies]

Hello @genzgd, good idea ! I got something like :

SELECT
    query,
    exception
FROM system.query_log
WHERE (exception != '') AND (event_time >= '2024-08-16')

Query id: af829311-a81f-4eb0-91a0-ccb30177a97e

Row 1:
──────
query:     EXCHANGE TABLES __dbt_exchange_test_0_6ba9cdd65ba911efb5164aefc927b229 AND __dbt_exchange_test_1_6ba9cdd65ba911efb5164aefc927b229
exception: Code: 497. DB::Exception: user: Not enough privileges. To execute this query, it's necessary to have the grant SELECT, DROP TABLE ON dbt.__dbt_exchange_test_0_6ba9cdd65ba911efb5164aefc927b229. (ACCESS_DENIED) (version 23.8.4.69 (official build))

So I went to system.users and saw that my user had not the same rights as me. However, this is not normal to have such an error message that blurred the real problem. Is there a possibility to change this and make it more reliable ? I let you guys close the issue then 👍

[genzgd]

Agreed that we should be catching that error and printing something more useful in the logs. We'll take a look.

Super ! Thanks @genzgd !
