> TestLogFragments.test_log_fragments is failing due to missing a log entry:
> {noformat}

> This started happening after the "IMPALA-8974: Fixed a bug when create kudu
> managed table without HMS" commit went in. That commit adds a test that
> restarts Impala in a frontend test. The problem is that it runs
> start-impala-cluster.py without arguments, whereas bin/run-all-tests.sh runs
> start-impala-cluster.py specifying the --log_dir. This would put the log
> files in a different location (/tmp?).

> [https://github.com/apache/impala/blob/master/bin/run-all-tests.sh#L165-L167]
> In one run that hit this issue, there are two sets of impalad logs in the
> ee_test directory. One set starts at 06:40:22 and ends at 07:11:28. The
> second set starts at 09:45:25 and ends at 09:47:30. So, this is missing 2.5
> hours of ee_test log files, which matches the theory.
> This is also likely to impact other things like erasure coding or tests that
> run against the data cache.
> GVO doesn't hit this because the job that runs frontend tests does not run
> end to end tests.
