> The proposal is: similar to StatusGetOpts.GET_COUNTERS, StatusGetOpts.GET_DAG_DETAILS could be sent to the AM if the client needs details about the vertices for instance. Currently, Hiveserver2 cannot be sure about dag details (e.g. vertex ids), and there is a chance that by using e.g. vertex ids, some specific logic might be run after dag completion. Tez is not supposed to be aware of those actions, only supposed to provide an extensible dag data by the dag client for upstream applications.
