Hong Tang updated MAPREDUCE-1175:
---------------------------------
Priority: Blocker (was: Major)
> We should have a spec on JobHistory file format
> -----------------------------------------------
>
> Key: MAPREDUCE-1175
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1175
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Hong Tang
> Priority: Blocker
>
> Currently, JobHistory schema is specified in o.a.h.m.jobhistory.Event.avpr,
> it requires some guess work for me to understand the meaning of various
> records. Also, it would be nice to spec out the dependency among the events.
> This would make tools like rumen more dependable to parse job history logs.
