Allen Wittenauer commented on HDFS-1150:
----------------------------------------
Why can't it use the 'regular Hadoop RPC'?
Altho at this point, I just don't care about this jira. After talking with
someone on the Yahoo! side yesterday, it is pretty clear that the solution you
guys are building will require trusted root to all nodes to be usable. Those
of us that don't have such lax security in place will have to use a different
solution anyway.
> Verify datanodes' identities to clients in secure clusters

> Currently we use block access tokens to allow datanodes to verify clients'
> identities, however we don't have a way for clients to verify the
> authenticity of the datanodes themselves.
