Bikas Saha commented on YARN-1815:
----------------------------------

bq. The right fix should be to record the UnmanagedAM completion info also.
That is what I was suggesting. If the completion info for unmanagedAM is saved 
then upon recovery we will have the correct value. The code path for unmanaged 
and managed AM's should be identical (except for recovery perhaps)

> RM doesn't recover unmanaged AMs into its memory after restart
