Vertex move to INITED as long as its parallelism is determined, no null edges and root inputs are initialized. RootInputDataInformation handling is not a precondition of vertex move to INITED. We can't wait for all the V_INPUT_DATA_INFORMATION events available in INITIALIZING state, because it is not know how many V_INPUT_DATA_INFORMATION we may receive, it is determined by VM. So will allow V_INPUT_DATA_INFORMATION happens when vertex is initialized.
