-----------------------------------------
Saw this again in an unrelated patch:
[https://gerrit.cloudera.org/c/19344/]
[https://jenkins.impala.io/job/ubuntu-16.04-dockerised-tests/6773]
{code:python}
query_test/test_scanners.py:441: in test_mt_dop_skew_lpt
assert cnt_fail <= 5
E assert 7 <= 5 {code}
Attached the stdout that contains the profile: [^profile-stdout.txt]
> TestHdfsScannerSkew.test_mt_dop_skew_lpt is flaky

> The test can fail with:
> {noformat}
> query_test/test_scanners.py:428: in test_mt_dop_skew_lpt
> assert cnt_fail < 3
> E assert 3 < 3
> {noformat}
> We need to fine-tune the test to deflake it.
