> S3A Retry Multiple S3 Key Deletion
> ----------------------------------

>                 Key: HADOOP-14239
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14239
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/s3
>    Affects Versions: 2.8.0
>         Environment: EC2, AWS
>            Reporter: Kazuyuki Tanimura

> When fs.s3a.multiobjectdelete.enable == true, It tries to delete multiple S3 
> keys at once.
> Although this is a great feature, it becomes problematic when AWS fails 
> deleting some S3 keys out of the deletion list. The aws-java-sdk internally 
> retries to delete them, but it does not help because it simply retries the 
> same list of S3 keys including the successfully deleted ones. In that case, 
> all successive retries fail deleting previously deleted keys since they do 
> not exist any more. Eventually it throws an Exception and leads to a job 
> failure entirely.
> Luckily, the AWS API reports which keys it failed to delete. We should retry 
> only for the keys that failed to be deleted from S3A
