Vinod Kumar Vavilapalli commented on YARN-975:
----------------------------------------------
Looks good overall. One file per app is reasonable. We already use TFile for
log-aggregation, so yeah it is good to pick that up too.
Regarding the implementation, see JobHistoryEventHandler. There we flush based
on two triggers: An upper limit on unflushed records and a time-based trigger.
We can add one more trigger: Application state change.
