Alexey Serbin commented on KUDU-2511:
-------------------------------------
As it turned out, the problem was in {{kudu::ParseVersion()}} -- the function
could not parse input string {{1.8.0-xxx-SNAPSHOT}}, effectively disabling the
movement of RF1 tablet replicas. However, the test asserted on a movement of
at least one replica in that scenario, failing as the result.
> The SingleReplicasStayOrMove scenario of the kudu-admin-test is a bit flaky
