Steve Moist commented on HADOOP-15006:
--------------------------------------

>what's your proposal for letting the client encryption be an optional feature, 
>with key? Config

If s3a.client.encryption.enabled=true then check for BEZ if exists encrypt 
objects, else no encryption for the bucket.  Or if the BEZI provider is 
configured as well rather than just the flag.

>Is the file length as returned in listings 100% consistent with the amount of 
>data you get to read?

Yes.

>I'm not going to touch this right now as its at the too raw stage

That's why I submitted it, for you and everyone else to play with to evaluate 
if this is something that we should move forward with.  If needed I can go fix 
the broken S3Guard/Committer/byte comparison tests and have yetus pass it, but 
the actual code is going to be about the same.

> This is for the proposal to introduce Client Side Encryption to S3 in such a 
> way that it can leverage HDFS transparent encryption, use the Hadoop KMS to 
> manage keys, use the `hdfs crypto` command line tools to manage encryption 
> zones in the cloud, and enable distcp to copy from HDFS to S3 (and 
> vice-versa) with data still encrypted.
