Sharad Agarwal updated MAPREDUCE-817:
-------------------------------------
Attachment: 817_v1.patch
This patch;
- Adds the getHistoryFile() api to JobStatus
- As soon as the job history file is moved to HDFS, the entire job
datastructures are removed from the memory, barring JobStatus object. JobStatus
objects are kept in RetiredJobs cache with default cache size 0f 5000.
- Retired jobs table is added to the Jobtracker UI, which will show the last
100 jobs in reverse "finish time" order. Perhaps later we can add the
pagination to show more jobs. The job id links to the Job history page for that
job.
- On accessing the job history file via UI, the history info is loaded and put
in the LRU cache, default size being 5.
- The "Completed" and "Failed" tables will show up in the UI only if there are
jobs which have completed but not yet "Retired".
> Add a JobClient API to get job history file url
