[~jonathan.bender] I think this bug was introduced by my change a couple of months later: MAPREDUCE-6892. Some new fields were introduced the jhist records. Is this urgent? I can take a look at this next week.

> In the event of an MRAppMaster recovery, the Job History file gets an event of the following form:
> {code:json}
> {"type":"JOB_KILLED","event":\{"org.apache.hadoop.mapreduce.jobhistory.JobUnsuccessfulCompletion":{"jobid":"job_1532048817013_xxxx","finishTime":1534521962641,"finishedMaps":0,"finishedReduces":0,"jobStatus":"SUCCEEDED","diagnostics":{"string":"Job commit succeeded in a prior MRAppMaster attempt before it crashed. Recovering."},"failedMaps":0,"failedReduces":0,"killedMaps":0,"killedReduces":0}}}
> {code}
> The issue seems to be around the SUCCEEDED job status for a JobUnsuccessfulCompletion:
> https://github.com/apache/hadoop/blob/e0f6ffdbad6f43fd43ec57fb68ebf5275b8b9ba0/hadoop-tools/hadoop-rumen/src/main/java/org/apache/hadoop/tools/rumen/JobBuilder.java#L609
> Which fails to find the enum here:
> https://github.com/apache/hadoop/blob/e0f6ffdbad6f43fd43ec57fb68ebf5275b8b9ba0/hadoop-tools/hadoop-rumen/src/main/java/org/apache/hadoop/tools/rumen/Pre21JobHistoryConstants.java#L50
> I'm not sure if this is an error with the Rumen parser or if the job history file is getting into an invalid state.
