Jason Lowe commented on YARN-1352:

Ah, good point.  I'll file a separate JIRA to handle saving that state.

As for this JIRA, I believe it will be covered by the combination of YARN-1354 
and YARN-1337.  As applications are recovered it will notify the 
LogAggregationService, and as active and completed containers are recovered it 
will also notify the aggregation service.  If the application did not finish 
aggregating then it will attempt to aggregate the app's container logs again.
