Jason Lowe commented on MAPREDUCE-4559:
---------------------------------------

Part of the difficulty here is that the ApplicationMaster is responsible for 
moving the job history file to a place where the history server picks it up.  
If the ApplicationMaster is killed abruptly or crashes, this move does not 
occur and therefore the history server will never see the job history.
                
> Job logs not accessible through job history server for AM killed due to 
> am.liveness-monitor expiry
