>    Affects Versions: 2.6.0
>            Reporter: Rushabh S Shah

> 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
