             Summary: impala-shell can output the "Fetched X row(s)" line before the actual results
                 Key: IMPALA-11337
                 URL: https://issues.apache.org/jira/browse/IMPALA-11337
             Project: IMPALA
          Issue Type: Bug
          Components: Clients
    Affects Versions: Impala 4.2.0
            Reporter: Joe McDonnell


In some scenarios, we are seeing that the "Fetched X row(s)" message is output before the actual data:
{noformat}
Query: SELECT * FROM test_table ORDER BY id DESC
Query submitted at: 2022-06-02 23:53:48 (Coordinator: https://coordinator:25000)
Query progress can be monitored at: https://coordinator:25000/query_plan?query_id=9d47858d6659cb87:2ccbdcdf00000000
Fetched 1 row(s) in 1.59s
0	john	10{noformat}
The "Fetched X row(s)" message is going to stderr and the results are going to stdout, so this is not covered completely by the current tests. Nonetheless, we should expect the "Fetched X row(s)" output to happen after the results data is written.

We should add tests for this case and make sure that stdout is flushed prior to writing the "Fetched X row(s)" output.
