Siddharth Seth commented on MAPREDUCE-2675:
-------------------------------------------
Bobby, took a quick look at the patch. Will try it out a little later.
getAllJobsInternal was using PartialJob with information from the JobHistory
file name to have a reasonable listing page load time. Using getJob() instead
will cause each jobHistory file to be read from hdfs and parsed - and a very
high load time if there's a lot of jobs. FileNameIndexUtils has the current set
of fields which are part of the JH filename.
Minor stuff
- addToLoadedJobCache should not require synchronization
- some of the debug messages could be removed / wrapped with debugEnabled
checks.
Looks like some basic tests will be added by MR2676.

> The main page of the Job History Server is based off of the Application
> Master code. It needs to be reformatted to be more useful and better match
> what was there before.
> - The Active Jobs title needs to be replaced with something more appropriate
> (i.e. Retired Jobs)
> - The table of jobs should have the following columns in it
> - Submit time, Job Id, Job Name, User and just because I think it would be
> useful state, maps completed, maps failed, reduces completed, reduces failed
> - The table needs more advanced filtering, something like
> http://datatables.net/release-datatables/examples/api/multi_filter.html This
> is to match the previous search functionality.
