    Affects Version/s:
> Integrating Hadoop Vaidya with JobHistory Server
> ------------------------------------------------
>                 Key: MAPREDUCE-3202
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3202
>             Project: Hadoop Map/Reduce
>          Issue Type: New Feature
>          Components: jobhistoryserver
>    Affects Versions:, 1.0.0
>            Reporter: vitthal (Suhas) Gogate
> At present jobdetailshistory page served by JobHistory Server provides elementary job
analysis through link "Analyze This job". Hadoop Vaidya provides a detailed analysis of the
M/R job in terms of various execution inefficiencies and the associated remedies that user
can easily understand and fix. Integrating Hadoop Vaidya with JobHistory server would really
improve the usability of this tool and also benefit many naive users understanding various
performance problems and/or best practices violations associated with their job.
> Integration would also aim at providing users a convenient interface where they can manage
the existing rules as well as write their own new rules. 
> During my tenure at Yahoo, Vaidya tool was successfully deployed in production analyzing
tens of thousands of jobs every day with lot more useful rules than the sample ones present
in the contrib project. Many of these rules are open sourced already (big thanks to Yahoo!
MAPREDUCE-1530) but yet to integrate with the tool.
> I will add more design details for this feature in near future as work towards getting
prototype running.. Any thoughts/comments are welcome.
