Jason Lowe created MAPREDUCE-4767:
-------------------------------------
Summary: AM should flush AMInfos to history file
Key: MAPREDUCE-4767
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4767
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: applicationmaster
Affects Versions: 0.23.4, 2.0.2-alpha
Reporter: Jason Lowe
When the ApplicationMaster starts up and generates (and potentially recovers)
AMInfo records for the history file, those events should be flushed to disk in
case the AM crashes badly. Failure to do so means the AMInfos could be lost
and the previous AM attempts lost upon recovery. See discussion in
MAPREDUCE-4729.
