Chris Douglas commented on HDFS-11026:
--------------------------------------
bq. The non-deterministic decoding exception needs to resolved before
integration.
I'm having trouble reproducing it. [~ehiggs], what version of the Oracle JDK
are you using? I tried Oracle 1.8.0_92, 1.8.0_121 and openjdk 1.8.0_121. All
throw NegativeArraySizeException.

> {{BlockTokenIdentifier}} currently uses a {{DataInput}}/{{DataOutput}}
> (basically a {{byte[]}}) and manual serialization to get data into and out of
> the encrypted buffer (in {{BlockKeyProto}}). Other TokenIdentifiers (e.g.
> {{ContainerTokenIdentifier}}, {{AMRMTokenIdentifier}}) use Protobuf. The
> {{BlockTokenIdenfitier}} should use Protobuf as well so it can be expanded
> more easily and will be consistent with the rest of the system.
> NB: Release of this will require a version update since 2.8.x won't be able
> to decipher {{BlockKeyProto.keyBytes}} from 2.8.y.
