> 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.
