Junping Du commented on MAPREDUCE-5485:
---------------------------------------
bq. Junping Du, there are some findbugs and ut failures, mind checking ?
The unit test is unrelated and just fixed in MAPREDUCE-6533. The fingbugs
warning belongs to wrong checking as
org.apache.hadoop.mapred.FileOutputCommitter.isCommitJobRepeatable(Context)
override the right method in parent abstract class (it wrongly recognize to
override another abstract method). So I think we should ignore these warnings.
> Allow repeating job commit by extending OutputCommitter API

> 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
