Subject Re: Not information in Job History UI
Date Mon, 03 Mar 2014 19:46:50 GMT
Note that node manager will not keep the finished applications and only
show running apps,  so the UI won't show the finished apps.
 Conversely, job history server UI will only show the finished apps but not
the running apps.

bq. there are no job logs generated on the server that is running the job.
by default, the local logs will be deleted after job finished.  you can
config yarn.nodemanager.delete.debug-delay-sec, to delay the deletion of
the logs.
