[~xiaochen]: Mind reviewing the latest patch.
Hopefully the last patch.

> The kms client appears to have no retry logic – at all. It's completely
> decoupled from the ipc retry logic. This has major impacts if the KMS is
> unreachable for any reason, including but not limited to network connection
> issues, timeouts, the +restart during an upgrade+.
> This has some major ramifications:
> # Jobs may fail to submit, although oozie resubmit logic should mask it
> # Non-oozie launchers may experience higher rates if they do not already have
> retry logic.
> # Tasks reading EZ files will fail, probably be masked by framework reattempts
> # EZ file creation fails after creating a 0-length file – client receives
> EDEK in the create response, then fails when decrypting the EDEK
> # Bulk hadoop fs copies, and maybe distcp, will prematurely fail
