Subject [jira] Commented: (HADOOP-239) job tracker WI drops jobs after 24 hours
Date Sun, 06 Aug 2006 17:58:15 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-239?page=comments#action_12426073 ] 
            
Sanjay Dahiya commented on HADOOP-239:
--------------------------------------

How about providing an additional JSP for job history. Current JSP's are using live data (not
persistant), they will be significantly changed if we read from log file as well as live jobtracker
in them. It will be cleaner if we dump the job log in a file and read the file in a separate
JSP, linked from current page. Comments ?

> The jobtracker's WI, keeps track of jobs executed in the past 24 hours.
> if the cluster was idle for a day (say Sunday) it drops all its history.
> Monday morning, the page is empty.
> Better would be to store a fixed number of jobs (say 10 each of succeeded and failed
jobs).
