Ewan Higgs updated HDFS-6708:
-----------------------------
Fix Version/s: 3.0.0-alpha3
Release Note: StorageTypes are now encoded in the BlockTokenIdentifier to
ensure that the intended StorageType for writes is not tampered with on it's
way through the Client to the Datanode.
Status: Patch Available (was: Open)
If HDFS-11026 is merged, this will need a rebase which I am happy to do.
> StorageType should be encoded in the block token
