Description

• Users should be able to download ATS data pertaining to a DAG from Tez-UI (more like a zip file containing DAG/Vertex/Task/TaskAttempt info).
• This can be plugged to an analyzer which parses the data, adds semantics and provides an in-memory representation for further analysis.
• This will enable to write different analyzer rules, which can be run on top of this in-memory representation to come up with analysis on the DAG.
• Results of this analyzer rules can be rendered on to UI (standalone webapp) later point in time.
