> * Manifest committer is not resilient to rename failures on task commit 
> without HADOOP-18012 rename recovery enabled. 
> * large burst of delete calls noted: are they needed?
> relates to HADOOP-19093 but takes a more minimal approach with goal of 
> changes in manifest committer only.
> Initial proposed changes
> * retry recovery on task commit rename, always (repeat save, delete, rename)
> * audit delete use and see if it can be pruned
