Elek, Marton commented on HDDS-1409:
------------------------------------
Thanks [~candychencan] to take care about this issue.
Can you please help me to understand the problem and how is it fixed? It if it
was just a wrong assertion number how is it possible that it is passed most of
the time (it's a flaky test). For example it's passed for me locally even
without this change.
