Aleksey Yeschenko commented on CASSANDRA-9035:
----------------------------------------------

[~Stefania] We'll mark that formally deprecated in 2.2 (in NEWS.txt if nowhere 
else), and stop supporting that behavior in 3.0.

A separate JMX {{nodetool blacklistdatacetnersforthints}}, or something with a 
better name, in 3.0, will be added.

> Fix hinted_handoff_enabled yaml setting

> 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.
