-------------------------------------
Summary: Capture distanceFromRoot and high/low priorities for the
vertex in ATS
Key: TEZ-3755
URL: https://issues.apache.org/jira/browse/TEZ-3755
Project: Apache Tez
Issue Type: Improvement
Reporter: Rajesh Balamohan
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 directly compute this at the
time of generating the dot file in DAGAppMaster.
