Andrew Wang updated HDFS-7181:
------------------------------
Attachment: hdfs-7181.001.patch
Patch attached. It's hard to unit test this, since it requires having the
unlimited strength JCE installed, which has export restrictions.
I tested this manually by creating a 256bit key, creating a new zone with this,
and writing and reading some files. I tested with JKS, going to do a quick KMS
test as well.
