Ashutosh Jindal commented on YARN-2193:
---------------------------------------
During applicationMaster start up, JobHistoryEventHandler initializes the
writer. This is one time initialization. If this fails because of NN problem,
then none of the events are written.
In this issue, because of NN safemode, writer is not initialized. Only
Job_Finished event is written. At historyserver, it parse the jhist file.
Job_Finished event does not contain all the fields. So, some of the field are
missed.
> Job history UI value are wrongly rendered
