Bikas Saha commented on TEZ-993:
--------------------------------
[~hitesh] [~zjffdu] Any opinions on the priority of this jira wrt other
advanced stuff/testing being done wrt recovery? Testing may not be affected if
it considers only the external visible effects of recovery but adding more
features to Tez may mean getting this cleaned up will be harder with time.

> Currently RecoveryService storage logic knows a lot about the DAG like which
> dag is pre-warm and does not need to be stored, which events needs special
> treatment etc. This kind of logic couples the DAG and the storage more than
> is probably necessary and can be a source of complications down the road. The
> storage should ideally be simply storing a sequence of arbitrary records
> delimited by a marker.
