> There are chances MRAppMaster crush during job committing,or NodeManager
> restart cause the committing AM exit due to container expire.In these cases
> ,the job will fail.
> However,some jobs can redo commit so failing the job becomes unnecessary.
> Let clients tell AM to allow redo commit or not is a better choice.
> This idea comes from Jason Lowe's comments in MAPREDUCE-4819
