Ivan Fedotov commented on IGNITE-8085: -------------------------------------- Also I want to clarify what was done in this ticket. Start remote node via ssh has next logic: in StartNodeCallableImpl script [1] to start node and session for this [2] are formed. If info about successful start node was found in logs, ClusterStartNodeResultImpl.isSuccess() returns true, otherwise IgniteException "Remote node could not start. " will be thrown [3]. I suppose that tests failed due to there is not enough time to check logs and although remote node was started, exception is thrown and tests fail. I increase time and iterations for check and tests became green, locally (600 times) and on TC(100 times). I think this fact confirmed my assumption.
