[100%] innodb_stress.innodb_stress               [ fail ]
        Test ended at 2019-06-20 16:06:07

MTR's internal check of the test case 'innodb_stress.innodb_stress' failed.
This means that the test case does not preserve the state that existed
before the test case was executed.  Most likely the test case did not
do a proper clean-up. It could also be caused by the previous test run
by this thread, if the server wasn't restarted.
This is the diff of the states of the servers before and after the
test case was executed:

How to repeat:
./mtr --suite=innodb_stress

Suggested fix:
It looks like innodb_stress.inc needs rpl_end.inc.
