László Bodor updated TEZ-4279:
------------------------------
Description: Similarly to StatusGetOpts.GET_COUNTERS,
StatusGetOpts.GET_DAG_DETAILS could be set to the AM if the client needs
details about the vertices. 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.
> Support some dag details in DagClient
