Steve Loughran updated MAPREDUCE-7474:
--------------------------------------
Description:
* 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
