> We found that [test_alter_table_recover()|https://github.com/apache/impala/blame/master/tests/metadata/test_ddl.py#L1026] could finish the execution within 10 seconds with JDK 17 when enable_async_ddl_execution is False and thus the check in the [else branch|https://github.com/apache/impala/blame/master/tests/metadata/test_ddl.py#L1079C12-L1079C12] could fail. Don't know it has something to do with JDK but maybe we could reduce the expected execution time a little bit to make the test less flaky.
> {code}
> # In sync mode:
> # The entire DDL is processed in the exec step with delay. exec_time should be
> # more than 10 seconds.
> #
> # In async mode:
> # The compilation of DDL is processed in the exec step without delay. And the
> # processing of the DDL plan is in wait step with delay. The wait time should
> # definitely take more time than 10 seconds.
> if enable_async_ddl:
> assert(wait_time >= 10)
> else:
> assert(exec_time >= 10)
