László Bodor updated TEZ-4279:
------------------------------
Summary: Support some dag/vertex details in DagClient (was: Support some
dag details in DagClient)
> Support some dag/vertex details in DagClient
> --------------------------------------------
>
> Key: TEZ-4279
> URL: https://issues.apache.org/jira/browse/TEZ-4279
> Project: Apache Tez
> Issue Type: Improvement
> Reporter: László Bodor
> Assignee: László Bodor
> Priority: Major
>
> 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.
