Rajesh Balamohan updated TEZ-3755:
----------------------------------
Description:
Currently {{distanceFromRoot}} is only available in info log. Scheduler does
not provide much info on the high/low priority of the vertices. It would be
good to capture these info in ATS, so that Tez-UI can render it in DAG details
page. This will help in understanding whether some vertices should have been
scheduled earlier than the other in complex DAG.
Vertex distanceFromRoot is computed as a part of
{{SourceVertexStartedTransition}}; it may not be possible to directly compute
this at the time of generating the dot file in DAGAppMaster.
