Aleksey Yeschenko commented on CASSANDRA-9035:
----------------------------------------------
bq. The existing yaml parameter, hinted_handoff_enabled, does it still need to
support the list of enabled DCs like mentioned in the description or can this
list too be removed?
Ideally it would for the duration of the transitional period. But given that we
are targeting this change for 3.0, we can just deprecate it in 2.2, with a
proper notice in NEWS.txt for both 2.2 and 3.0, and not complicate 3.0.
> Fix hinted_handoff_enabled yaml setting

> Key: CASSANDRA-9035

> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Stefania

> 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.
