Aleksey Yeschenko commented on CASSANDRA-6157:
----------------------------------------------
Why exactly do we have csv in our yaml when yaml has perfectly good built-in
support for lists?
And there is zero reasons to collate the two config options (enabled/disabled +
list of DCs) in one yaml param. This should've been a boolean global
{{hinted_handoff_enabled}} param plus a separate yaml list for the HH DC
blacklist - {{hinted_handoff_disabled_datacenters}}
[~kohlisankalp] or [~lyubent] - can you guys find time to open a new ticket and
fix this at least in 3.0 or should I assign to someone else? Thanks.

> 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.
