Lyuben Todorov commented on CASSANDRA-6157:
-------------------------------------------
Tested with a dc named "dc 2" (setting looked like: {{hinted_handoff_enabled:
dc 2,dc1}}) As for adding the csv parser, all that is left is to add the
parser's licence to C*_HOME/lib/licences. I've [posted a
branch|https://github.com/lyubent/cassandra/tree/hints_per_dc] with the license
and patch 5 applied (commit on 6341148f971fbf6b73e891f8784b389fc8054c20). Also
fixed imports in o.a.c.config.Config

> Cassandra supports disabling the hints or reducing the window for hints.
> It would be helpful to have a switch which stops hints to a down data center
> but continue hints to other DCs.
> This is helpful during data center fail over as hints will put more
> unnecessary pressure on the DC taking double traffic. Also since now
> Cassandra is under reduced reduncany, we don't want to disable hints within
> the DC.
