Favored nodes is 'there' in apache hdfs, just not used/tested. The last bit is
still to be hooked up in apache hbase. It has been a TODO for a long while.

Cool, we should mark this as a TODO in HydraBase integration as well.

What I mean by package-doc is something like this
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/package-summary.html#package_description
(yes, javadoc but at package level giving overview... I think this might be
all that is needed in FSM case since it is 'easy' to read at the method/class
level... its just the high-level story that needs a bit of filling in).

Sure.

I understand why you've not done splits for messages but you think it will be
possible out in apache hbase atop what you have here? Can be later... just
asking.

I think it will be slightly involved because essentially we are stoping the
parent quorum and starting two daughter quorums. This could be done as a
configuration change, and we can do this in the next HydraBase version.

On swift, yeah, the annotations are nice but it'd be a headache having thrift
for one communication channel and pb/hbase-rpc for another. We can help w/ the
conversion here since we have a bit of experience, np. Its fine as swift for
now.

Yes, I understand the concern. Let's follow up on this later then.
Thanks.
