Andrew Wang updated HADOOP-10936:
---------------------------------

    Attachment: hadoop-10936.001.patch

Patch attached. I didn't actually run the KMS to test this, but did run KeyShell which has
output like this:

{noformat}
blahKey has been successfully created with options Options{cipher='AES/CTR/NoPadding', bitLength=128,
description='null', attributes=null}.
{noformat}

> You need to download unlimited strength JCE to work with 256-bit keys. It'd be good to
change the default to 128 to avoid needing the unlimited strength JCE, and print out the bitlength
being used in places.
