Subject [jira] [Commented] (CASSANDRA-9035) Fix hinted_handoff_enabled yaml setting
Date Mon, 22 Jun 2015 13:12:01 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14595889#comment-14595889

Stefania commented on CASSANDRA-9035:
-------------------------------------

Thanks, I'll add {{disablehintsfordc}} and {{enablehintsfordc}} to nodetool and remove the
optional DC list form {{enablehandoff}}.

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?

> 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.
