Subject [jira] [Created] (MAPREDUCE-4767) AM should flush AMInfos to history file
Date Thu, 01 Nov 2012 22:48:12 GMT
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.
