Rohith Sharma K S commented on MAPREDUCE-5441:
----------------------------------------------
One scenario I have doubt,
what if current running application master attempt is last( i.e isLastAMRetry
is true)? I think it is better to validate isLastAMRetry and set external state.
> JobClient exit whenever RM issue Reboot command to 1st attempt App Master.
