Description

          throw new TezUncheckedException(vertex.getLogIdentifier() +
          " has -1 tasks but does not have input initializers, " +
          "1-1 uninited sources or custom vertex manager to set it at runtime");

IMO, for this kind of verification we could do it in client side (DAG.verify)

The following are the message on the client side, the reason that Client could not get the real status of DAG is that Tez AM is killed due to this vertex init error
