------------------------------------
Summary: test_alter_table_recover could finish less than 10
seconds with JDK 17 when enable_async_ddl_execution is False
Key: IMPALA-12522
URL: https://issues.apache.org/jira/browse/IMPALA-12522
Project: IMPALA
Issue Type: Test
Reporter: Fang-Yu Rao
Assignee: Joe McDonnell
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)
