Patricio Echague commented on CASSANDRA-2045:
---------------------------------------------
Jonathan/all, the hints delivery seems to be broken in trunk. However,
triggering manually the deliverHints() through JConsole effectively delivers
the hints to the replica and remove them from the sender.
> Simplify HH to decrease read load when nodes come back

> Currently when HH is enabled, hints are stored, and when a node comes back,
> we begin sending that node data. We do a lookup on the local node for the row
> to send. To help reduce read load (if a node is offline for long period of
> time) we should store the data we want forward the node locally instead. We
> wouldn't have to do any lookups, just take byte[] and send to the destination.
