Billie Rinaldi commented on ACCUMULO-958:
-----------------------------------------
Michael, if the patch available for HADOOP-9333 is accepted, would that change
your approach (putting aside the question of which Hadoop versions will have
it)?

> There are some cases where users want encryption at rest for the walogs. It
> should be fairly trivial to implement it in such a way to insert a
> CipherOutputStream into the data path (defaulting to using a NullCipher) and
> then making the Cipher pluggable to users can insert the appropriate
> mechanisms for their use case.
> This also means swapping in CipherInputStream and putting in a check to make
> sure the Cipher type's match at read and write time. Possibly a versioning
> mechanism so people can migrate Ciphers.
