Hitesh Shah commented on TEZ-2758:
----------------------------------
bq. Right, It is not necessary to write DAGFinishedEvent to recovery file after
we write it to summary log. We won't read recovery file as long as summary log
says completed. That means the append API could be removed. Will post a patch
soon.
Lets write the dag finished to both summary and recovery log but after that for
any retrospective failures, only write to summary but not to the main log ( if
the outputstream has been closed ). Does that work?
