Aleksey Yeschenko commented on CASSANDRA-9035:
----------------------------------------------
{{disablehintsfordc}} to add a single DC to the blacklist and
{{enablehintsfordc}} to remove a single DC from the blacklist (if there). Not
accepting lists, but the end user can presumably use loops.
> Fix hinted_handoff_enabled yaml setting

> Key: CASSANDRA-9035
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9035
> Project: Cassandra
> Issue Type: Sub-task

> Priority: Minor
> Fix For: 3.x
>
>
> As discussed in CASSANDRA-6157, at the moment we have a single parameter
> {{hinted_handoff_enabled}} that can be either a boolean or a csv list of
> enabled data centers.
> We should have a boolean global {{hinted_handoff_enabled}} param plus a
> separate yaml list for the HH DC blacklist -
> {{hinted_handoff_disabled_datacenters}} to be checked when the global flag is
> on.
> Backward compatibility with the existing approach should be kept.
