> To be able to truly fix issues like MAPREDUCE-4819 and MAPREDUCE-4832, we 
> need a 2 phase commit where a subsequent AM can be sure that at a specific 
> point in time it knows exactly if any tasks/jobs are committing.  The job 
> history log is already used for similar functionality so we would like to 
> reuse this, but we need to be sure that errors while writing out to the job 
> history log are now fatal.
