Xiao Chen commented on HDFS-10899:
----------------------------------

Patch 15 uploaded, still based on PATCH-14705.. 

Addressed all [~jojochuang] comments above (I think), as well as some issues 
found during internal testing:
- fixed {{listReencryptionStatus}} to track by inode, and also filter out 
snapshots
- added fault injectors and related unit tests for failure handling.
- throttling improvements

> Add functionality to re-encrypt EDEKs

> Currently when an encryption zone (EZ) key is rotated, it only takes effect 
> on new EDEKs. We should provide a way to re-encrypt EDEKs after the EZ key 
> rotation, for improved security.
