Siddharth Seth commented on MAPREDUCE-3966:
-------------------------------------------
Instead of separating the caches, we could just cache the parsed jobInfo
instances (currently caching CompletedJob), and construct CompletedJob,Task etc
when required. That's not too expensive and would simplify the cache.
> Add separate cache for CompletedJobs with tasks loaded and without tasks
> loaded in JobHIstoryServer

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver, mrv2
> Affects Versions: 0.23.1
> Reporter: Vinod Kumar Vavilapalli
>
> After MAPREDUCE-3901, we should have separate caches for list of CompletedJob
> with tasks loaded and list of CompletedJob without tasks loaded. Once we have
> separate cache, we should increase the cache size for the list which doesn't
> load tasks.
